        Comments about K&N Replacement Air Filter:

        I like these filters because I only have to buy one.never have to replace it. I live on a dirt road,and I clean it once or twice a year. I've been buying them for years for my vehicles and they always fit well and I notice a slight gain in power..mostly when accelerating on the expressway. I've never seen a fuel milage gain..but never a loss either. so all that being equal, this filter will pay for itself in a couple years saving me the cost of buying a paper one for 15-20 bucks a whack twice a year. I think that alone makes them worth it. A recharge kit will last for a couple years.

          Marketing ploy and a poor choice for such a small sized engines. Better choice would be Drive Works or Purolator.
