    Great filter value

    I like these filter because they are two separate filters, not two density foams that are bonded together. That makes them easier to inspect, clean and oil.

    You'll need some air filter oil, but its a very good product would buy again.

    Only thing you'll need for it is some air filter oil. Very good product.
