Just purchased a 2011 370Z with 6 speed manual transmission...bought this after I totaled my 1991 Alfa Romeo Spider Veloce...presently having the wheels powder coated a flat black, than want to put either a K&N or Nismo cold air intake system...any suggestions on which one to go with...this is actually my 3rd Z car..I had a 1984 turbo and a 1990 twin turbo..hope the new one is as much fun...
