Each hidden breather is O-ringed at the heads and exits at the mouth of the injector or carb to provide efficient engine breathing without the need for external hoses or hardware.

Standard red filters are pre-oiled, washable, and feature four layers of surgical grade cotton to deliver optimum filtration while maintaining maximum airflow.

A radius air inlet provides unobstructed airflow for maximum performance, and a one-piece backing plate integrates the hidden breather routing for a clean, compact installation.

All necessary hardware and installation instructions are included, and the kit accepts Arlen Ness® Stage I round covers only for '01-17' Twin Cam Delphi EFI and Twin Cam CV carb models.
