Not available from S&S anymore but I'm reasonably sure the filter itself was made by K&N. Had the S&S set up on an '06 Hammer.
Like 11ZNL; said what happened to yours? They are serviceable and last indefinitely.
Well, I wanted to service the filter yesterday. Removed the seat, tank, etc... got to the filter cover and the hex bolts were spun out. Had to pull off the TB with the intake asssembly still attached. Major PIA. I took the intake to a machine shop to remove the bolts this morning. Since they no longer make these, I'd like a backup just in case.
