A Pre-Oiled filter is an awesome Idea. Just open the package and put the air filter on the bike. Even comes with plastic gloves so you don't get your hands all sticky. Now I don't have to oil the filter until after its first use and cleaning. :-)
A high quality, 2-stage foam air filter that is pre-treated with No-Toil Evolution biodegradable filter oil. It is perfectly oiled and ready to use right out of the bag.
