Would a Air intake be a good investment? About how much horsepower gain would I get out of it? I am thinking of buying one so help me out a little bit. Cold Air or just regular, What kind, and Where the cheapest place to buy it from is. Preciate it.

 

Welcome to the .Org.

Hrm.... FAQ? If I had a penny for everytime this was asked.

Investment.... no.
Improvement.... yes.

Improve your car.

It has noticable gains and works well.

2-5 HP Max. And as the car learns the new air flow, it will slightly reduce from when you first install it. If you have other mods (like exhaust) as well, then your gains will vary. Most go up, but some do go down.

There is a big debate over which one to get.
The pop-charger (a.k.a. WAI) produces the best overall numbers. Many companies make them: Frankencar, JWT, Stillen, etc
The CAI has the most torque, but lower HP numbers. The only true CAI is made by Place Racing. You'll have to drill a hole for the PR CAI. Most people don't want to drill, so they get the "CAI" that isn't a CAI... made by Injen.

Cheapest place to buy them is in the Group Deals forum. Other than that, try contacting the companies directly, or figure out which one you want and call around for prices.
