yes they are legit, but the filters that come with them aren't able to handle larger amounts of turbo vacuum. so if your not pushing any boost the filter is fine if your looking to get just a adapter then your good as well. while your at it take the MAS screen out to make it a equivalent of a performance MAS.
no im not pushing any boost, i just found it hard to believe that the filter on ebay would give you a 5-7 hp increase, i know by allowing more air into the engine it produces more hp, but i trust the guys on this site, so i guess we will see, if not, then it was only 10 bucks..lol
