I beleieve I have sent feedback on this product already. Superior quality, fast shipping, never had to deal with any unexpected delays. So far my purchases from K&N have been up to par. I will continue shopping with them as long as they provide the same quality I've come to expect.

Just changed the oil on my bike and replaced the filter with K&N oil filter. Easy to order and arrived on time. I hear good things about K&N products so I ordered a reusable air filter. My bike seems to run better. A little more power on acceleration. Sounds great.
