Just got my K&N from the local stealership today, don't ask for the price..... stealership should clue everyone in. Anyway the install is straight forward and I tested the new filter in place, definitely gave the FZ6 more "umph", I also have the TB cannons on. Haven't installed the PCIII yet, having trouble downloading the fuel maps from the site. I will however work on that this weekend and see how that works. I can honestly say the bike is feels different now, even though the TB was installed prior to the new filter. I noticed the same thing with my old civic when I replaced the stock air filter to a K&N brand, best bang for the buck in the long run........ and it will run for a long time. I believe the guarantee is 1 million miles with proper care and maintainance of the filter.
