Precision Works Vented Oil Cap & Fittings – Honda K-Series V3

Precision Works Vented Oil Cap & Fittings – Honda K-Series V3

The Precision Works Vented Oil Cap V3 is a smart, clean solution for improving crankcase ventilation on Honda performance engines. Designed with a newly engineered single-piece oil cap and an enlarged internal baffle housing, the V3 significantly reduces crankcase pressure while helping control oil vapor more effectively than previous designs.

This system eliminates the need to modify or weld bungs onto your valve cover, making it one of the easiest and cleanest ways to add 10AN fittings for proper crankcase ventilation. It is a true bolt-on upgrade that installs directly in place of the factory oil cap, saving time while maintaining a professional, OEM-plus appearance.

Machined from billet 6061 aluminum and finished in black anodizing, the Precision Works Vented Oil Cap V3 is built for durability, performance, and long-term reliability. When paired with an external oil catch can system, it provides a complete solution for managing blow-by in both street and track-driven builds.
