Chrome Steel Round 1 3/8" Clamp-On Breather with Washable Filter for Crankcase Ventilation and Engine Dress-Up

This clamp-on oil filler cap is designed for compatible valve cover oil fill openings and helps complete a clean, finished engine appearance. The chrome-plated steel construction provides a bright dress-up look, while the twist-on design allows for secure installation on compatible valve covers.

The 1 3/8" neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. Use it for hot rod, muscle car, truck, and performance applications where crankcase pressure control and appearance matter.

Verify neck size, PCV routing, hose barb size, grommet compatibility, and valve cover opening before installation.
