Great product quality as usual from K&N, won't go anywhere else. The only issue was that my air filter was not shipped with the sealant suggested in the install instructions. I sent an email to K&N questioning what I could use in it's place, like a di-electric grease. But they quickly shipped out a tube of K&N sealant. Wasn't expecting that type of response, just an email stating something I could use in it's place. Thanks.

This is for a slightly oval (the round filter becomes not round when snapped into place, but still within the overall dimensions of the filter) S&S air cleaner assembly for Harley-Davidson carburetor-ed big V-Twins. I tried finding this at my two local H-D dealers and they had no clue on how to get it, other than to suggest buying a new $400 air cleaner assembly. The numbers molded onto the filter do not match any K&N part number, thus making getting it identified a little more difficult. I assume this is because it is a custom filter made for another company to incorporate into a product. When I took the old filter off and put it back into a round shape to get the dimensions and punched them into the K&N search tool, this model came right up, was delivered promptly, and fits perfectly. Hat's off to K&N

The addition of the E-3226 filter as with all KN products made a great deal of difference in terms of performance and the sound of the bike on acceleration.  The bike now sounds like a small block when I run through the gears and keep the rpms up.  Great product as always.
