Intake For 2.4l, FYI Options

[NY-09GTS]

In my quest to find the perfect intake for my needs, I did a lot of research. I decided on a SRI, that also utilizes the stock fresh air inlet, for two reasons. One, because I think it will give me better throttle response off the line/from a stand still due to the warmer air under the hood, and two, because once you get going the fresh/colder outside air blows thru the stock inlet and blows fresh/colder air onto the filter, giving you the gains in the higher rpm range.

But when trying to pick one out, what I found was that all the current intakes on the market by the major manufactures, except for RRM, will not work correctly with the 2.4L engine. The current intakes out there are all specifically designed for the 2.0L engine which does not need as much air as the 2.4L, and has a different mass air sensor.
I contacted AEM, K&N, RRM, Injen, and Fujita. I ended up speaking with aem and k&n, on the phone and rrm thru email. Injen and fujita did not return emails and I did not contact them via phone. Here’s what I got straight from the manufactures mouth:

AEM: They said, their current CAI will not work with the 2.4L engine, it will not provide enough air and the mass air sensor on the 2.4L would have fits. They also said they weren’t even sure if it would bolt up correctly. I asked if they had plans to make a CAI for the 2.4L and they said as of right now there are no plans.

K&N: They said their current SRI will bolt up, but they were not sure that it would provide enough air which would result in the engine running lean. They also said they did not test their SRI with the 2.4L because it was made for the 2.0L, so didn't know if you'd gain hp's or possibly lose power. They also said if you did buy one and use it on the 2.4L that they would not honor their million mile warranty. I asked about plans for a 2.4L version and they said they didn’t know of any plans right now.

RRM: They said they tested several different SRI designs and the one they offer on their website is specifically made for the 2.4L. They also said anything made for the 2.0L would starve the 2.4L engine of air. I asked about a dyno for their 2.4L intake but they did not answer that question in the email.

Injen and Fujita: I got no response from either company. I emailed them both twice and got no response.

Just some info for anyone looking for an intake for the 2.4L engine.

the difference between the 2.4L and 2.0L engine air requirements are minimul. any stock cone filter will work on ANY car that you can put it on. for reference, i added the SAME "power adder" intake cone on my NA 3000GT as i did on the stealth Twin Turbo engine. the engine runs fine either way.
get yourself a piece of pipe that puts your cone where you want it, and put a cone K&N filter on the end of it. it is the cheapest best performance out of an intake you can really get. you can spend 200-300 dollars on a name brand full cold air intake and get about 1 more HP out of it.

just some food for thought (IMG:style_emoticons/default/thumbsup.gif)

honestly the 2.4L works just fine with the injen 2.0 intake. i know because I have tried it. if my engine was starving for fuel my car would bog, my mAF sensor would throw a CEL and everything would just be crazy.


but this is not the case, it works fine and performs the same. ive tried it on my brothers 08 and on my 09 2.4l gts. you get the same CAI bog at the lower RPM but once your above 2.5k it works just as it should. Injens design is the exact same except the diameter near the MAF sensor is a little wider, honestly HOW MUCH MORE air do you think is flowing through there ? Either way if you dont have an intake yet then get the Injen CAI for the 2.4L engine for those who already have the 2.0 intakeo n their 2.4 engine just stick with it not worth trying to change it out

[lancer0220]

heres some food for thought.

the snorkel on the stock airbox for the 2.0 l and 2.4l engine has anyone compared them ?

well im pretty sure, 99.9% sure they are exact same and same with the airbox mount so if the 2.4L engine did need a wider intake pipe then
mitsubishi definitely missed that one, heh. i will compare the two this weekend as my brother is coming in from college to visit.

[NY-09GTS]

I'm just reporting what the manufactures of the intakes told me.

I realize the air requirement difference between the two engines is minimal, but we can all agree that it is the different. My point is if kn, aem, injen, etc dyno their intake on a 2.0 and say the get X amount of gain, will you get the same gain on the 2.4? The manufactures of the product say no or they don't know.

The injen one, who I never got to speak to, actually makes more sense to me that it wouldn't work correctly or the same as on a 2.0L. First they do not have a version for the 2.4L engine. All they sell, or any site sells, that I seen is one for 2008+ 2.0L engine. And also, because injen uses its MR technology which actually changes the dia of the tube to control air flow. If the air flow rate for the 2.4 is different it would make sense that the one designed for the 2.0 may not work on a 2.4 like it would on a 2.0 engine. Sure I've read where people say they put the injen intake on their 2.4 and it works fine, but no one has a dyno to prove it. Unless you have a dyno done which shows your HP/torque gain and also shows the air/fuel mixture your just guessing that it works ok because your not throwing CEL. Get a dyno done and that will answer the question on the injen intake. Could be that your only getting 2hp gain on the 2.4 where the 2.0 gets 8hp, until you dyno, your just guessing.
And K&N not honoring their warranty is also a clue for me that they may know something that we don't.

I don't think it's just the dia of the tube that comes into play, its also the length and shape that controls the air flow as well and in injens case the MR technology too. As far as comparing the two engines stock tube dia, that's a good idea. But if they are the same maybe that would explain why the 2.4L engine runs so rich. If you look at my dyno pinned in this forum for the 2.4L engine you'll see it runs very rich with the stock intake, maybe because its just not getting enough air. Mitsubishi may have known but for costs reasons just kept the same one from the 2.0 figuring many will swap out the stock one anyway.

Feel free to fire back here, I just wanted to post this to get some discussion going on the topic for the 2.4L engine.

[EngRWW33]

If they make intakes specifically for the 2.4l they will gain maybe 2hp over the 2.0 version. They cannot tell you what to expect or anything like that because they don't want to come up with some BS off the top of their heads. Reputable companies don't like to do that stuff.

Injen will have a 2.4l version out soon, but again, I bet they post 2-3 hp gain over the 2.0 version. The 2.0 version will work fine on the 2.4 engine, but is not optimal. They will make the optimal version for the 2.4 and sell them seperately.

In the end there will be difference, but those differences will be minimal.

[Lewiman06]

on an N/A engine the air gets drawn threw the intake. the engine takes what it wants and the ONLY THING the intake filter does is remove dirt from the air its taking.
regardless of engine size, its all the same. there will be a slightly gettter gain out of an intake on a 2.4 just because of how it all works. and as for a 2.0 gaining 8HP from an intake alone, i call BS all day long. your average gain from an intake on a NA engine is about 3-4.

the only thing it does is allow the air into the engine smoother, THATS IT!!!!!!!!!!!!!!!!!
you WON"T get a CEL, YOU WON"T throw any codes.
a universal cone filter can be used on anything from a 1.6 NA engine all the way to a 5.0 mustang. same filter...... IT JUST FILTERS AIR! nothing more.
the only difference is the material, air flows better threw K&N filtering material then threw stock air filter material. thats why you see a gain. also the piping made from SMOOTH parts allows the air to be "drawn" in faster, smoother and cooler.

so like said before, any smooth pipe, plus a K&N cone or even a 25 dollar cone from auto zone and you'll see for the most part the same 2-4HP increase, and you can also spend 300 for a higher quality material, but i don't think you'll see much more of a difference.

YES THEY DO HAVE A 2.4L version also i dont expect to get the same gains since my car already has +16hp over the 2.0, this isnt the only lancer forum in the world. Its out there. Also i wouldnt waste money dynoing my car to compare to your dyno or someone elses dyno because all dynos are differnt. ALso i wouldnt waste money dynoing my car with and without intake because honestly I dont think im getting +8hp like injen claims for the 2.0. I get better MPG, better top in performance, it looks good and the filter is reusable, honestly thats all i care about. I would only dyno my car if i was going to drop 5k and turbo it.

Thank you.


hence the reason im sticking with the 2.0l version i only paid 250 shipped for. overpriced yes b ut i like the look.


also Ny09gts, im speaking from someone who has owned n 08 es and an 09 gts. drove the 08 for 35k miles and now have 20k on my 09, i think i have some experience with both engines.

[sordid]

A SRI/CAI for a 2.0L will still flow better than the stock air box for a 2.4L -- especially the SRI being shorter. Anybody that has gone from one to the other can tell that right away as soon as they blip the throttle.

[afterdarq]

Actually, K&N sells the exact same SRI for both the 2008 2.0L and the 2009 2.4L. It is the exact same Typhoon 69-6544TS that they list for the two engines. Go to the website and see for yourself. And that makes sense, they are basically the same engines. Plus, I am pretty sure the stock intakes are also the same. Also, the gains for the bigger engine should be greater IMO.

Ya that's really the point I was trying to make, I guess I should have said optimal and not wouldn't work correctly. I know intakes for the 2.0 will will work but not at optimal performance, so in my opinion, why spend money on something that isn't going to get me what I paid for. I heard rumors of a injen 2.4 version, but since they didn't return my emails I don't know if and when, and since I'll only have this car till next year I didn't want to wait maybe all summer before they came out with one. (getting ralliart next year). And ay I agree the differences will be minimal, but 2-3 hp is 2-3 hp. It all adds up in the end.
I will say though that when I did speak with aem and kn, they both said in not so many words that if you put their 2.0L version on your 2.4 and it runs lean and ruins the engine that they are not responsible. So part of this discussion was to see what others thought, if their might be a chance of it running lean.

I wasn't talking about filters, I know what they do. Bigger engines need more air, so not sure what you mean by its all the same regardless of engine size. I never thought injens claim of 8hp gain was valid either. But that's what their dyno says. I think its BS too. Most dynos I've seen in real life show average of 5hp from an intake so ya I agree with you there. And ok I hear what your saying and agree the intake does only smooth/keep cool the air flow and that it doesn't really let it get more of less air per say. But the question then comes up, why did the manufactures I talked to basically say it may run lean if you use the 2.0 version on a 2.4. Are they just covering the butts or something?

[lancer0220]

Are they just covering the butts or something?

Precisely, the fact is they dont know and dont wnat to spend the $ to R&D it. They made one for the 2.0 that distributors will sell for the 2.4 cuz it fits and thats fine thats all they need.

[NY-09GTS]

YES THEY DO HAVE A 2.4L version also i dont expect to get the same gains since my car already has +16hp over the 2.0, this isnt the only lancer forum in the world. Its out there.

Do you have a link to where I can buy a injen intake for the 2.4 engine? They don't have one listed on their site and I can't find one on any of the sites I usually buy from. I heard it was still in development. I never said do a dyno and compare to mine that makes no sense. I meant dyno yours stock then dyno it with intake and see what you get. I like to see the gains I'm getting for the money I'm spending. I realize most don't do that, but to me its worth it to get dynos for any performance mods I do. I know lots of "tuners" that claim all kinds of horsepower with nothing to back it up. I can back mine up. But anyway it's nice to know you dont get any cel's with yours. Thanks for the input.

[EngRWW33]

^^Not out yet.

And that makes sense, they are basically the same engines. Plus, I am pretty sure the stock intakes are also the same. Also, the gains for the bigger engine should be greater IMO.

I saw that on their site, it says it for both engines, so that's why I called them since their dyno was only for a 2.0l. That's when kn started talking about how its not made for the 2.4, and they wont warranty it, and if may ryun lean, etc. That's what promted this whole thread. I wanted to get others opinions.

[Lewiman06]

there SHOULD really be no design difference at all.
an NA engine "drawns" what it wants threw the filter, IT WILL NOT RUN LEAN! trust me.
and even if the did make a whole NEW intake for the 2.4, i'd guarentee it has the EXACT SAME FILTER!
i don't know how else to explain it or make it any clearer, the2.0 will work just fine, the exact same way, and with no problems what so ever on the 2.4L engine.
if the throttle body connection (where the intake connects to the engine) is the same size as the 2.0 then run the exact same intake and it will run perfect.
the engine won't get "starved of air" thats rediclious, and WON'T RUN LEAN! i don't even see how that could happen at all.

[EngRWW33]

the main issue with the fujita and the cel it caused on our engines was that it makes the engine run LEAN... Others have got the codes read adn posted findings on other threads here and elsewhere.
filters will make no difference, no arguements here.

the fujita didnt make the car run lean by design it made it run lean by a fault that did not allow the maf sensor to sit properly. i know plenty of ppl runnin the fujita intake modified to sit the maf sensor properly.

heck i made my own SRI modding a mazda 3 intake and it ran fine for 10k miles until i got my 09 gts. i never once got a CEL or had a decrease in MPG or performance.


end the end its just piping to a filter. the reason i have the 2.0 is i got it for 250 shipped the 2.4l.is going to cost 325-400 depending on which vendor you get from plus shipping.

i dont bother messing with a dyno because honestly paying $60 to get PROOF of a 5hp gain is useless and pathetic. Its safe to assume I have gained 3-5 hp argue all you want but im not wasting 60 bucks to prove such a small gain. i also dont claim my car has that gain for a fact if someone asks how much does your cai get you ? i dont spit numbers i merely say about the same as any other cai.if the person knew cars they would know that on an NA 4 cyl engine thats producing 168hp stock, a cai is only going to help so much, its about all the same.
