I want to replace my stock air intake system with an aftermarket cold air intake system on my 03 A4 because I realized the stock one looks like its suffocating my engine.

Anyways 2 things...

1, where and what kind of intake should I get?

2, how do I install it myself?


Thanks!!

 

do a little research. everyone says the "cold air" kit actually pulls in hotter air than stock. just go with a K&N stock replacement

 

You may be right. For a small engine it might be too much air intake.

 

It's not that it's too much, it's just that the factory intake system is capable of far more flow than the engine draws. Still, the drop-in K&N means you never buy another filter again.

 

if u remove the stock intake you will replacing it with a hot air intake. Turbo being right by the side of the intake with a very thin heatshield equals power loss.

 

The air is going to heat up regardless because it's being pressurized in the turbo, which also happens to be smoking hot.
