2005 A8 performance upgrade help
 

I am looking to increase the horsepower of my 05 A8. I have searched for a air intake or any other method but was not able to find anything. I am not looking to turbo charge it or anything like that just air, chip exhaust etc.
Any help is appreciated.

Don't both with an intake, you will only lose horsepower.

Is there a sticky with a list of bolt-ons. For us future Audi owners, I need to know the list of mods.

www.audifreaks.com has a sticky i made for it in the A8 section.
