I've been noticing a lot of talk about the removal of the stock cai leading to the filter box. I removed this piece after reading the segment on the free wai mod. In addition i removed the resonator instead of taping over the hole. By removing this resonator the smaller box in front of the filter box now has 2 holes for intake (stock cai and resonator connection). This is further improving the air flow to the intake. In addition the empty space where the resonator was is now opened up and it is a tunnel straight to down to the underbody in front of the wheel well. i think this may be pulling cold air from beneath the car and may offer a few more hoeses. I still only have a stock filter but plan to get a k&n filter soon. But someone else could dyno the 2002 3.5 (do not have acces to dyno equipment) with these mods and see if there is any increased H.P. I anyone can try this and let me know if it is better than just removing the stock cai.
