  1. A5 & S5 Topics
    I installed a new air filter and now when I start the car it starts for a second then instantly dies. If I rev the car it will keep alive for a bit longer but then ultimately dies once the throttle is stopped. Any help?
  2. S5 Performance & Mods
    Has anyone installed a K&N Air Filter? i thought it would be an easy, cheap mod that might add a little horsepower but i didn't know if anyone had any problems with them or screwed with the dealer warranty. Has anyone noticed any power gains?
