59-86 SBC Bowtie Wire Looms 2pcs

The PROFORM 59-86 SBC Bowtie Wire Looms 2pcs (Part Number 141-638) is a valve cover-mounted spark plug wire management system designed for small block Chevy engines. These aluminum and chrome-finished looms feature the iconic Chevy Bowtie logo and are engineered to organize and secure 7–8 mm spark plug wires with clean, professional routing. This two-piece kit provides a factory-style appearance while protecting wires from heat, abrasion, and engine debris.

The looms mount directly to the valve covers, eliminating wire sag and tangling that can compromise ignition performance. The aluminum construction offers lightweight durability, while the chrome finish resists corrosion and complements modern engine bay aesthetics. Proper wire routing reduces electromagnetic interference and maintains consistent spark delivery under load—critical for reliable cold starts and sustained throttle response across varied operating temperatures.

Builders and enthusiasts restoring small block Chevy engines—whether for street machines, vintage trucks, or performance applications—rely on these looms to achieve a finished engine bay appearance while protecting ignition hardware. The Bowtie branding appeals to traditionalists committed to authentic Chevrolet styling. Compatible with 7–8 mm diameter spark plug wires, this kit is ideal for anyone upgrading factory wire management or replacing worn looms on existing builds.

Small block Chevy engines remain the foundation of American automotive culture, and attention to detail—including wire loom routing—separates a professional build from a neglected installation. These PROFORM looms deliver both function and heritage appeal in a straightforward, bolt-on package.
