PQY Spark Plug Wire Loom Holders for Chevy Small Block SBC 350 — Anodized Aluminum, 2-Pack, Adjustable 7–10mm

PQY Spark Plug Wire Loom Holders are aluminum wire-management brackets designed to organize and protect spark plug wires on Chevy Small Block (262–400) V8 engines, keeping wires away from headers and heat.

These linear spark plug wire looms from PQY are made specifically for classic and modern Chevy small-block engines (1959–1986) and provide a tidy, secure routing solution for four ignition wires. The anodized aluminum construction resists corrosion and vibration while the adjustable holes accept common 7–8mm wires and can expand to about 10mm when needed. Each kit includes two looms and a hex key for quick on-car adjustments.

How do these looms improve engine bay organization?

They group and route spark plug wires into a fixed, predictable path so wires don’t contact hot headers, belts, or pulleys. That reduces abrasion risk and keeps the engine compartment looking finished.

• Secures four wires per linear bracket for a clean layout
• Keeps wires off high-heat areas to reduce wear
• Prevents tangled or crossed wiring for easier maintenance

Are these compatible with my Chevy 350 (Small Block SBC)?

Yes—the design targets Chevy Small Block engines from 262 to 400 cubic inches produced between 1959 and 1986, which includes the popular Chevy 350. The mounting geometry and wire spacing fit typical SBC header and valve cover configurations.

• Designed for Chevy Small Block 262–400 V8 engines (1959–1986)
• Works well with common header and valve-cover setups on SBCs
• Two looms per kit to cover both sides of the engine

What sizes and wire types will these looms accept?

The standard hole size accommodates most 7–8mm spark plug wires used in aftermarket and original ignition systems. You can loosen the supplied hex screw to slightly widen the holes up to about 10mm for thicker boots or wire sleeves.

• Default fit for 7–8mm spark plug wires
• Adjustable to approximately 10mm using the included hex key
• Works for common wire and boot profiles used on SBC builds

What materials and durability features does the kit offer?

The looms are machined from sturdy aluminum alloy and finished with anodizing to resist rust and corrosion. The material and fasteners are chosen to withstand vibration and heat common in engine compartments without deforming.

• Sturdy aluminum alloy resists impact and vibration
• Anodized finish offers corrosion and rust resistance
• Built to remain stable under engine-heat cycling

Who is this for: Enthusiasts restoring or modifying Chevy small-block engines who want a neat, durable way to route spark plug wires. Whether you’re building a period-correct SBC, upgrading headers, or tidying a hot-rod engine bay, this PQY kit gives a secure, adjustable solution that improves longevity and appearance without complex installation.
