You can tell a difference right away after putting this in, just getting in the throttle a little bit and the front tire wants to come up, Can't wait to get on a good straightaway.

Installed this air filter in my FZ6 and it makes noticeably more power. The engine is fairly small, and has a very wide rev-range. I have zero empirical evidence to support this claim, but, the whole rev range seems more robust and uninhibited.

I wasn't really expecting a performance change with just a new air filter, but I was surprised. Not only does the bike sound more throaty, it revs more smoothly and doesn't bog down as easily if I up-shift too soon.

Great product as are most of K&N products. It made my bike run and sound better. The air intake is much more effective now. My '09 Yamaha FZ6 is a missile! Couldn´t be happier with such a great quality product! Thanks for taking such good care of your customers K&N!

I recently installed a YA-6004 k & n filter in my FZ-6 and I've seen a lot of difference..The sound was awesome, acceleration  also and RPM's were going up in a smoother way. I am very  very  happy and I am recommending it to everyone !!
