if you have more air flow through the pipe and air filter, wouldnt you need to increase the fuel amount at the same time to get the horsepower that some people claim? or does the computer pick up on more air flow and adjust for more fuel by itself?

Someone else on here did a PVC with header wrap: that's prob the direction I would go to cover it and separate heat.

yaa i read about that ,, i was wondering if a magnaflow muffler with 4" cold air intake would make any noticable power / i think it all could be done under 500.00 /and would it be worth it?

You DEF can do it for under $500 ish and you would notice a HUGE difference.

Here is the link to the PVC CAI that Nick did

I plan to keep my K&N but make an elbow to delete the Res box out of PVC.

Re: cold air intake
 
so how much of a hp increase would you see ?

JeepCoop 09-10-2011 11:49 AM

A good amount. Def noticeable. What motor do you have?

Re: cold air intake
 
Well, With my 3.7L, K&N says +15hp.. So I can only assume removing the res box would only help.

It'll help a lot. Especially when combining an exhaust. Less resistance and more flow. :headbang:

I made mine with alloy piping and silcone elbows. Works perfectly, looks great and cost a fraction of the price.
