Review on 🏎️ Boost Horsepower & Performance: K&N Cold Air Intake Kit for 1995-2001 AUDI (A4, A6, A6 Quattro, A4 Quattro) by Josh Andrews

No more body limitations. The sound is also convincing. The ability to breathe in much more air is immediately apparent. Increased horsepower and mpg (as long as you don't step on the ground). I've searched the internet for cheaper air intake systems but none of them have met the K&N million mile guarantee. Plus, it got there for free in 2 days with Revain Prime. Be warned: this kit is not CARB-free, so keep the factory air intake to ensure the smog gets through.
