K&N filters generally don't help out anything. I would stick with the stock filter if the objective is the most hp. Just buy the stickers and skip the filter. The stickers are the secret.

The K&N's are great for cars, but modern sportbikes dont really gain from them at all,they are already good.

I put one in my 02 to try it myself, and noticed no difference at all.
They eventually pay for themselves as they are re-usable though, so it's not a total waste to get them.

Same here, I've had em in my last 2 cars with somewhat noticable gains (sounds better too) but have yet to do the bike. Just doesn't seem worthwhile from what who's tried it says.

Does the new 03 636 take the same air filter as the old zx6 and if it does do u think its a good idea to throw a K&N in my new 03 636 i think it would help out the hindle slip on.
