Polaris Pro R Billet Breather Block Upgrade

Upgrade your crankcase ventilation system with the Polaris Pro R billet breather block, designed to replace the restrictive factory cast assembly that uses a 5/16” bundy style fitting. This Pro R breather block upgrade allows you to connect a much larger -10 AN fitting, making it ideal for high-performance and aftermarket breather setups.

Precision machined for strength and reliability, this Polaris Pro R breather block features a -10 ORB port and comes standard with a -10 port fitting installed, giving you a clean and secure connection point for upgraded breather systems.

This is the same billet breather block included in TPR’s Pro R breather kit, making it a trusted solution for performance builds.

If you are upgrading to a larger breather line or building a custom setup, this Polaris Pro R -10 AN breather block is the proper foundation.
