K&N filter recharge
Put roughly 33k miles on it before cleaning and oiling for the first time-I went a little longer than I should have based on the crap I had to clean out of it. Purchased the K&N recharge kit for about $20. Most likely will get a few cleans/oils out of it. Had to spend some time on their site trying to make sure I didn’t over oil it. The website offers some good info in their Expert blog section.
