Order and packing and quality of the product was great. Please improve your website and the ability to choose to allow delivery if not home based on signing the slip that you leave when an attempt is made. I had to drive into Brockton to pick it up.

The K&N Replacement filter is an easy job to do and comes with a new gasket to make sure it gets a tight fit to the breather housing. It is also pre-lubed with the correct amount of filter oil but I still bought the kit to clean and re-lube it when the time comes. Not sure on the mileage between cleanings yet or the gas mileage, still need to run a few tanks of gas out but so far the bike does seem to run better. No modifications needed when replacing the stock filter with the K&N.
