Factory intakes are designed in such a way that restricts the clean air flow to the engine and allow for more exhaust air (EGR) to reach the intake. The Big Boss Intake is made to allow up to 15 percent more clean air into the engine while still mounting in the factory position with the factory hardware. We do this by eliminating the “necked down design” that the factory gives you and replace it with an open design. The manifold will allow for cooler intake air temperatures and an additional 15-20hp. Like all PDI products, they are designed to make more horsepower and create more efficiency so you save money while making the drive more enjoyable.

  • PDI diesel treats you like family. They take the time explaining things to you. I had no idea they could make my semi-truck diesel run that strong. If performance is on your mind—as far as I'm concerned—there's nothing like PDI diesel.
