MY BROTHER JUST BOUGHT HIS FIRST AUDI A4 B6 2002...HE WANTS TO PUT A COLD AIR INITAKE BUT SOME PEOPLE ARE TELLING HIM THAT A AFTERMARKET AIR BOX WOULD BE BETTER ..WHAT DO YOU GUYS THINK...????ALSO WOULD A AFTERMARKET AIR BOX ADD MORE HP..???

 

Start a new thread without using all caps. Thats the most e-nnoying thing to do, ever. Do a search on the subject while youre at it. Spanks.

 

First of all, turn off your caps lock key.

What engine does he have?

Neither a CAI or aftermarket airbox will give him much power at all. The best option would be a cone filter with a really good heat shield.
