TC Bros. Breather Bolts for Harley-Davidson Twin Cam

Stock airboxes on Harley-Davidson Twin Cams integrate a provision for crankcase breathing through the cylinder heads. Eliminating the airbox to run an aftermarket air cleaner also eliminates the hollow breathing bolts.

  • Fits all Twin Cam 1999-2017
  • Available in Raw Machined or Black finish
  • Permits use of many aftermarket air cleaners (including all TC Bros. units)
  • Air cleaner support brackets available separately; required for most aftermarket air cleaner installationsĀ 
  • Made in USA
  • CNC-machined from 6061 aluminum

These bolts offer an unobtrusive, alternative crankcase venting option when installing aftermarket air cleaners on your Harley-Davidson. They are CNC-machined from 6061 aluminum and offered in two attractive finishes. Stainless steel vent screens, stainless washers, circlips and foam filter elements are included. Sidestep ugly hoses and bulky breather filters with a set of TC Bros. Breather Bolts. Not legal for sale or use in California.
