Bowtie Slant-Edge Breather Cap Red Bowtie

The Bowtie Slant-Edge Breather Cap Red Bowtie is a precision-engineered crankcase ventilation component designed for serious engine builders and hot rod enthusiasts who demand reliable, authentic styling alongside functional performance. This push-in breather serves as a critical component in any custom engine's PCV system, allowing pressurized gases to escape the crankcase while maintaining proper engine breathing. Whether you're restoring a classic muscle car, building a street rod, or upgrading a performance engine, this breather cap delivers both form and function with its iconic recessed red bowtie logo that complements PROFORM's heritage aesthetic.

Constructed from durable aluminum with a hard chrome finish, the Bowtie Slant-Edge Breather Cap Red Bowtie features a slant-edge design that reduces turbulence and optimizes airflow characteristics within the valve cover cavity. The push-in installation method accommodates a 1-1/4 inch hole, making it compatible with standard valve cover configurations found across a wide range of classic and modern engine platforms. The reusable design ensures longevity and eliminates the need for frequent replacement, while the recessed red bowtie logo provides visual authenticity without compromising aerodynamic efficiency. Chrome plating resists corrosion and maintains a showroom-quality appearance through years of underhood exposure.

This breather cap is ideal for engine builders restoring vintage performance vehicles, street rod fabricators seeking period-correct details, and enthusiasts who refuse to compromise on quality or appearance. Installation is straightforward—simply push the breather cap into a prepared 1-1/4 inch hole in the valve cover until it seats firmly. Verify hole diameter and condition before installation to ensure a secure, leak-free fit. The compact footprint (4 x 2.7 x 5.85 inches) and lightweight construction (0.39 lbs) make it easy to integrate into tight engine compartments without adding unnecessary mass or complexity to your engine's breathing system.
