K&N RL-320B Replacement Air Filter Product Reviews

Tuesday, April 17, 2018 - Part RL-320B
Beautifully finished stock-style, custom air cleaner assembly. Fits nicely on the Linkert ('49 Bobber). I had a small search for a practical custom air cleaner, while keeping with the more conservative style of the factory original. K&N quality, performance and longevity are the reasons all but 1 of 12 bikes built utilized K&N filters (the only exception was an original '62 Pan with stock mesh filter.
