Black Breather Cap & PCV Valve Set - Suits 1.25" Valve Rocker Cover Filler Holes

• Complete breather and PCV setup - Includes black breather cap, black PCV valve, and matching grommets for a complete rocker cover ventilation refresh.
• Supports proper crankcase ventilation - PCV valve helps route blow-by gases and oil vapour back through the intake system.
• Clean black engine bay finish - Black breather cap adds a subtle dress-up look to performance and restored engines.

This black breather cap and PCV valve set is designed for most stamped steel and aluminium valve covers with 1-1/4" filler holes. The baffle-equipped breather cap provides a cleaner, lower profile look than many standard mushroom-style breathers, while the included PCV valve supports proper crankcase ventilation. Supplied with matching grommets, the set provides a snug, leak-resistant fit for both breather and PCV applications.
