HardDrive Breather Bolts


Use these brackets and breather kits when installing an aftermarket aircleaner. If a custom breather system is used, some support brackets are available without the breather system. Spacer 820-50525 can be used in conjunction with breather/bracket kit 820-50512 to mount aftermarket aircleaners with a CV/Delphi EFI bolt pattern to TBW models.

Doesn't fit a 2007 Sportster

By   on  Verified Purchaser

Does not fit a 2007 Sportster as described. The HardDrive Breather Bolts with Fitting are the correct size, but this set is a smaller diameter.
