I started racing motorcycles in the early 70's and as a greenhorn learned about K&N filters in the pits. I have K&N air filters on everything but my lawnmower. A restored 1977 RD-400 Yamaha, a 2007 Hummer, a 1999 Chevy p.u., a 1987 Honda ATV, and now my 2004 Polaris. They are the only air filters that I will pay money for.

I put K&N air filters on everything, a 2007 Hummer, 1999 Chevy P/U, a 1977 Yamaha and a 2004 Polaris ATV and I have used them exclusively since racing motorcycles in the 1970's. They are simply the best that there is. I have started many others on K&N including my oldest grandson. Great product.

I have used K&N filters for years on my Honda Goldwings. I recently needed a replacement for my Polaris ATV and saw that you had a filter for that - - now I'm good to go for another million miles! You quickly shipped me the perfect filter. Thanks.
