Well, I had bought a performance filter before, it improved a bit..but not that much...i switched it for a whole new intake system...I REALLY felt a difference there, it was said to give about 10-15hp, I also got this chip...installed it...sucked...but the installation instructions werent concise, so I redid it and felt even more power, about the same improvement as i did with the intake, so im guessin they put about the same amout on...I may have a lil more or a lil less than 185 tho, But thats a safe guess, I pretty confident that it's at least 185. Before any of these, I raced one of my friends who has the new eclipse (4 cylinder 162hp i believe)..it was close, and i was ahead by a lil bit. But i just wanted to know what is available for a 2.5L V6. It doesnt seem like there are that many mods for it but exterior...so im doin that right now.
you want that air intake to actually do something? get a custom header made for like $400 get the head ported and polished as well as the throttle body, intake mani, and plenum bored and port matched....then u can say like 185.....luckily for the 420a users companys like OBX sell performance packages that actually do what they say they will....like 500-600 dollars but still $600 for 190-210hp give or take how ur car was taken care of....that's not bad for an all motor avenger pushin it
