Bel-Ray Foam Filter Oil Liter

Last a lot longer than other oils best oil to use if ur racing or riding heavy

Started using this product after blowing up a bike at a GNCC race due to sucking in dust. Switching from spray on filter oil to the Belray Foam Filter oil. So far I have had the best of luck with this product. It is stickier and soaks deep into the filter to ensure no dirt can pass through. I always grease the rim of the filter as well just as a precaution.
