Ok, i want to get an Intake system and was wondering if anyone has the Stillen intake. I heard that you have to make a hole in the driver side fenderwall but i really dont want to. And where is the cheapest place to get intake.
Thanks.

 

Stillen Intake is just a Cone that replaces the stock air box, it sits right where your airbox is now. A Cold Air Intake aka CAI is tubing that runs down to your fender then through into the wheel well where the cone sits and sucks in air from outside the engine bay.

CAI will give you better low end and mid range power, while the stillen intake may give you a slight top end increase over the CAI.
The Stillen is usually about 40 bucks less than a CAI.
www.cattman.com
and
www.warpspeedperformance.com
are to that carry CAIs and Cattman carries the JWT Pop Charger which is similar if not better than the Stillen

 

if you don't wanna drill a hole in the car then you could get a Jim Wolf intake. It's not a CAI but from what my friend says his works great. you can find out more info here

 

Who makes CAI for 3rd gen. Maximas and about how much do they cost?

 

I guess you missed the reply above but check out www.warpspeedperformance.com for CAIs
