This is a question for those that ride Kaws. I am trying to help a buddy out who is new to the Sportbike community. How much do you pay for your oil filters? I believe he WAY over paid for his. Considering the one I bought for my RC-51 was a K&N and $12.99. He has a '03 ZX-6R? Anyone that can give me an idea of how much this filter would cost I would appreciate it. Then may have to post a "negative" about the dealer he bought his supplies from.
