Great filter, easy to fit and remove from my Honda Deauville 700. I buy 2 at a time to save the postage and cost of going to a shop. 2 filters last me the year as I clock up 16,000 miles a year. Also fitted the air filter which is doing a great job at 30,000 miles to date.

I was very pleased after installing my K&N filter on my 2014 Honda Accord Hybrid. It added a noticeable amount of power and it helped get rid of the engine lag. Also helped a bit with gas mileage. Great performance.

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.
