Has anyone actually noticed any difference at all , useing aftermarket air filters....some manufacters claim as much as 5 hp. gain over stock filters on the FZ6...boy I'd like to see some dyno specs on that ! Daryl
some manufacters claim as much as 5 hp.
I suppose that for K&N to make those claims they do some test on a ragged out engine and then tune it up and add their air filter: Voila! Instant 5 hp increase.
