Some low cost mods for the 4/4 just completed. Started with a wonderful combined air dam and scoop from Cain. Hooked up to a 70mm pipe running up to a K&N air filter kit replacing the air filter box. I also had the ECU remapped. More horsepower. More mid range torque and more noise without the afterburner popping from sport exhaust (without manifold/Cat section conversion which is expensive and may not pass emissions test here).
