This Chrome Breather Cap & PCV Valve Set is ideal for dress-up and functionality on performance or restored engines. Designed to fit most cast aluminium and stamped steel rocker covers with 1-1/4" filler holes Ø31mm, this set includes two quality grommets and a baffle-equipped breather cap with a sleeker profile than standard mushroom styles.

The mirror-finish chrome breather and steel PCV valve gives your engine bay a clean, refined look while supporting proper crankcase ventilation. The PCV valve helps remove blow-by gases and oil vapour from the engine, routing them back through the intake system instead of allowing pressure to build inside the crankcase. Included grommets provide a snug, leak-resistant fit for both breather and PCV applications.

Important

• Breather grommet tip can be cut to suit your installation or kept intact as a bung.
• Please confirm your rocker cover filler hole size before ordering.

• To install the PCV valve barb correctly, apply a small amount of silicone lubricant spray or soapy water inside the hose first.
