Product Details

Features

  • Chrome-plated steel construction resists corrosion in the engine bay long-term
  • Filter element supports crankcase ventilation and airflow
  • Fits 1.220" openings on compatible Chevrolet, Ford, and Chrysler valve covers
  • Twist-on design secures to compatible valve cover breather openings

Description

The Chrome Steel Twist-On Breather provides crankcase ventilation with a clean, chrome-plated finish for the engine bay. Steel construction with a chrome finish resists corrosion and holds up under engine heat, while the internal filter element supports proper airflow and crankcase pressure relief.

This breather is sized to a 1.220" opening and twists onto compatible valve cover breather ports — neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. It's commonly used on universal hot rod, muscle car, truck, and performance builds, including Chevrolet, Ford, and Chrysler V8 applications with matching valve cover openings.

Before installation, verify neck diameter, grommet size, PCV routing, and valve cover opening style, along with clearance around the rocker cover, coil, and hood.


Applications
Fits compatible twist-on valve cover breather openings sized to 1.220". Commonly used on universal hot rod, muscle car, and truck builds, including Chevrolet, Ford, and Chrysler V8 engines with matching valve cover openings.

Filter & Construction
Filter element inside a plain round chrome steel top — diameter 2 3/8", height 1 5/8". No grommet included, so the opening itself must accept the twist-on neck directly.
