25' Plug Wire Sleeve

The MOROSO 25' Plug Wire Sleeve (MOR72000) is a 25-foot fiberglass and silicone protective sleeve designed for spark plug wire management in high-performance and classic engine builds. This blue wire sleeve accommodates 7mm to 8mm diameter wires, providing thermal insulation and organization for ignition systems where wire routing and heat protection are critical to reliable operation.

The dual-material construction combines fiberglass durability with silicone flexibility, allowing the sleeve to withstand engine compartment heat while remaining pliable enough to route around tight spaces and engine components. At 25 feet in length, this sleeve provides enough coverage for complete multi-cylinder ignition systems or extended wire runs typical in street rod, restoration, and vintage performance applications. The 7mm-8mm internal diameter range accommodates standard domestic and import spark plug wire gauges without bunching or excessive slack.

Builders and enthusiasts working on custom ignition systems appreciate wire sleeves for their ability to bundle runs neatly, reduce electromagnetic interference, and protect wiring from abrasion against sharp edges or moving engine parts. The bright blue color aids in visual identification during engine work and troubleshooting. This product is sold as a continuous 25-foot roll, allowing users to cut and fit sections as needed for their specific application rather than buying pre-cut segments.

MOROSO is a recognized supplier of engine dress-up and ignition system components for classic car restoration and performance engine building. The 25' wire sleeve is a modular component that pairs well with matched spark plug wire sets and ignition upgrades in vintage hot rod and restoration projects.
