Improved Durability and Reliability

If you're building a purpose-built Duramax and airflow is holding you back, the PPE Race High-Flow 3-Inch Intake Bridge Manifold is the kind of upgrade that makes a real difference. Designed specifically for high-performance engines that demand more than what stock components can deliver, this raw aluminum intake bridge removes the factory intake heater—one of the biggest airflow bottlenecks in the system—and replaces it with a wide-open, 3-inch pathway that feeds your engine more air, more efficiently. Whether you're setting up a hot rod diesel, marine engine, or a competition rig, this manifold is all about delivering boost with fewer restrictions and lower EGTs. That translates to more horsepower, quicker throttle response, and cleaner combustion under pressure. The raw finish keeps things simple and functional—exactly what you'd expect in a no-nonsense racing application.

Designed for High-Performance Applications

Because it's meant for serious builds, this isn’t a direct bolt-on part. PPE designed this intake bridge with versatility in mind, so it fits a wide range of custom setups—but it will require some fabrication to get it dialed in for your specific engine layout. It’s also important to note that this component is for race use only, meaning it’s not street legal and isn’t intended for registered or off-road recreational vehicles. You’ll need to provide documentation to PPE confirming it’s being installed on a non-road-legal race vehicle. If you're after smoother airflow and the performance gains that come with it, and you're building a competition-grade Duramax setup, the PPE 3-Inch Race Intake Bridge is a smart foundation to support serious power.
