Excellent product.
Victor, Augusta, GA
I've been using K&N filters on my motorcycles, cars, and trucks for years. They always help the engine breathe more efficiently and give me slightly better gas mileage. They're easy to clean when needed and last the life of whatever vehicle or bike I put them on. Don't mess around - these filters are superior to anything else out there.
