Friday, September 18, 2015 - Part KN-401
I love being able to buy your product on line for a motorcycle that is almost 30 Years Old (1986 YAMAHA FJ1200), and I was excited that it came with the O rings; however the big O-ring was too big. It would not fit in the filter housing. I don't know if this was due to a cross reference error, or just a packaging error; after all the bike will be 30 years old in January. I wasn't upset and just added the big O-ring to a list of [Name Brand] I was ordering the next day. I would buy from you again.

I'm glad I decided to buy this high quality filter for my Honda Goldwing instead of something else. It gives me piece of mind knowing I'm using a K&N filter.

From start to finish K&N are the best there is. Not a lot more i can say if you want the best filter on the market, why go anywhere else?

Good, quality oil filter. It seems like I can really feel a difference in the performance of my motorcycle and oil is staying so much cleaner. I wish every business offered the same great service K & N does.
