I've decided to install a cold air intake, I was wondering if there is anything I should know about, any tuning I should have done, computer issues, engine light, really anything that's not obvious to the every day driver, any suggestion/tips are GREATLY appreciated !

Your stock intake is cold air........anything that pulls underhood air (just about every aftermarket) will take away power (by inhaling hot,underhood air).

Only thing you get (beyond a lighter wallet) is intake noise.

If you do change something, disco the battery during the install, reconnect afterwards......this allows the computer to reset itself around the new airflow characteristics.

For years with carb vehicles a heated air cleaner was used to vaporize the fuel, fuel droplets do not burn very well. Had two air intakes, one from under the hood, other piped from a fitting on the exhaust manifold with a thermostatic controlled valve to chose between the two to get 160*F heat. If the tube running to the exhaust fitting, the engine would run like crap.

Intake manifold doesn't need preheat, already preheated by the engine as the fuel injectors spray directly into it. For more intake air, the turbo handles this function,up to 35 PSI peak. If you play around with this from OE, more than likely will get poorer performance.

Actually feel an aluminum intake manifold would be superior to plastic, would conduct engine heat far better, but what can you say about plastic, far cheaper to manufacturer.

But gather it so expensive because you just can't buy the manifold, comes with injectors, TB, and other stuff.

Over 310 bucks.

Ha, if you want cold air, come to Wisconsin, like 30 below, not only get winter gas, but that cold air doesn't vaporize the fuel very well.

If you have a performance tune, that may require an adjustment by your tuning company(bnr, etc) or notification when ordering a tune that you have that modification.

Does that tune compensate for lack of fuel vaporization? Creating a problem that wasn't there before, so how can this be corrected by playing with code?
