A cat-back and a custom tune will do wonders for it.
Oh yeah? What did you put on?
The factory air box flows plenty of air. The real restriction is the factory air tube with all the noise cancelling built in. Airaid makes a replacement tube so you retain your factory air box and paper filter. I'd just leave the cone filter in place until its dirty then go from there.Ok got a couple more questions.
1. I've got some sort of cold air intake on here, it bothered me at first, but I've gotten used to the noise now. Is it worth keeping? A guy at work wants to trade his factory air filter setup for it. I'd rather not have the issues of dealing with the cone filter, I'd rather toss the old one out, and put the new one in and be good.
2. I picked up oil and a filter today, and noticed the filter (pf46e) is about the size of a lawn mower filter, is it worth finding a longer filter, or am I over thinking things? I know these are much better engines than even the TBI engines are due to technology, and therefore not as dirty and having much better machining tolerances.
