This is a heads up for everyone out there. I have visited various online autoparts sites and noticed that they have the wrong listing for the spark plugs for the 3.8l V6 cars. The gap is NOT .044" as mentioned on their sites, therefore the spark plug they have listed is wrong also. Here is an email I received from NGK, the manufacturer of the OE plug:
I just spoke with a Mitsubishi dealer about this. From what they show by application for this vehicle, FR6EI stock no. 2687 is correct. This plug will come out of the box close to .032. No further gap adjustment is recommended.
Not to mention the spark plugs that NGK has listed on their site is also the wrong heat range. They have a hotter plug listed. (with NGK plugs, the lower the number 4-5-6-7, etc. the hotter the plugs will run) That combined with a lot wider gap could be potentially hazardous to your car.
I am not sure why NGK hasn't changed this information, kinda curious because they even admitted that it was, in fact, wrong. Hope this helps someone out there before they waste a lot of money on a set of plugs.
