Turn Up The Power Without Melting The Essentials

When you’re pushing serious horsepower, engine bay temperatures start climbing fast, and that heat doesn’t play nice with hoses, wires, or anything remotely sensitive. That’s where the PPE 3-inch x 1-foot Heat Sleeve steps in to keep things cool and protected. Built for high-performance environments, this rugged sleeve is a simple but smart upgrade that shields fuel lines, vacuum lines, and electrical wiring from the punishing heat that builds around turbo housings, intercooler pipes, and exhaust components. Whether you're ripping through canyon roads or dialing in boost on the dyno, it's the kind of detail that prevents failure when things get hot. The silicone-coated fiberglass material not only looks tough but actually delivers, holding steady against temps up to 500 degrees Fahrenheit and surviving spikes as high as 2200. That means your setup stays safer, longer, and more reliable. It’s flexible, easy to slip over existing lines, and fits right in whether you’re running a race car, diesel truck, or weekend toy. If you're serious about performance, protecting the small stuff goes a long way.

Built For Heat So Nothing Gets Left Behind

The PPE 578013001 Heat Sleeve is designed for high-heat engine compartments where reliability matters most. Constructed from woven fiberglass and coated with high-temp silicone, it offers long-term heat resistance up to 500°F, with the ability to handle short bursts up to 2200°F. This makes it ideal for shielding critical components like coolant hoses, boost lines, fuel lines, and even delicate electrical harnesses from intense heat exposure. Its 3-inch diameter and 1-foot length offer a universal fit that adapts well to a wide range of builds. From drag cars to daily drivers with turbocharged systems, the sleeve is engineered to wrap easily around existing lines without requiring a full teardown. It adds a layer of heat protection where you need it most, especially near exhaust manifolds, turbochargers, or hot-side intercooler piping. With a simple install and rock-solid construction, it’s the kind of solution that solves a real problem without adding complexity.
