Turn Down The Heat And Turn Up The Performance

If you’re serious about getting more out of your Duramax, you know heat can be the silent killer under the hood. That’s where PPE’s Heat Shield Set steps in, bringing a practical, performance-driven solution to lower your intake temps and protect vital components. Whether you’re hauling heavy loads or just pushing your truck to its limits, keeping things cool means everything from better turbo response to a longer life for your wiring harness. This setup isn’t just about looks or marketing hype, it’s a real barrier against damaging heat, built to keep your performance consistent. The blanket design tucks in neatly over your high-flow manifolds and works hard without getting in the way. PPE makes it easy to get professional-grade results in your garage, and the difference you’ll feel in turbo spool and intake temp will speak for itself. It’s one of those upgrades you’ll wish you had done sooner.

High Temp Materials Designed For Real World Abuse

Engineered with durability in mind, the PPE Heat Shield Set brings serious thermal protection with materials that are rated for real-world performance. Each blanket is over half an inch thick and made from three layers of high-grade silica fabric that can handle continuous exposure up to 1800°F, withstanding short bursts as hot as 3000°F. This design isn’t just about insulation, it directly contributes to faster turbo spool by minimizing heat soak and improving thermal management around your manifolds. The blankets also serve a critical role in protecting nearby components like your wiring harness, sensors, and electronics from prolonged heat exposure. For those running high-performance builds or simply looking to extend the longevity of engine bay components, this set delivers both protection and a bump in thermal efficiency. Fitment is dialed in for 2001–2016 6.6L Duramax applications, making it a bolt-on upgrade you can trust to hold up under extreme conditions. This is one of those behind-the-scenes parts that quietly makes everything else work better.
