PPE Intercooler Piping Silicone Hose Kit , Duramax | 2011 - 2016

PPE Performance Silicone Hoses are engineered for serious durability, built with five layers of Nomex-reinforced fiber to handle demanding conditions. A fluorocarbon inner lining provides superior lubricity and strong resistance to fuel and chemical exposure, while the high-grade silicone construction keeps the hoses stable under continuous boost. Whether it’s -76°F cold starts or 437°F under-hood heat, PPE hoses maintain their shape and strength without ballooning or blowing out like factory hoses often do.

Designed to stand up to harsh environments, PPE silicone hoses resist oil, fuel, chemicals, UV damage, and ozone, making them ideal for heavy-use applications. With a wide selection of diameters and configurations, there’s a PPE hose to match nearly any system layout.

High-stress situations—like drag racing, sled pulling, or aggressive towing—create intense, rapid pressure spikes. PPE built these hoses to thrive under those extremes, delivering the reliability needed for competition while also serving as a robust upgrade for everyday driving.

Note: Because of the thick 6mm hose wall, you’ll need clamps that are ½ inch larger than the hose’s inner diameter for proper fitment.
