By opening up the manifold in key areas airflow will increase up to 35% leading to lower air intake temperatures resulting in power gains of up to 20hp. These direct replacement manifolds are simple to install and utilize factory hardware. Like all PDI products, the Big Boss intake manifolds will increase horsepower, torque, and efficiency to make your drive more enjoyable and save you money.

Increased Pulling Power & Better Fuel Mileage!!

We have installed several Big Boss Performance Tuners and Big Boss Intake Manifolds in our fleet. We are seeing anywhere from ½ MPG improvement in fuel economy to as much as 1¼ MPG improvement with both. Drivers are very pleased with the increase in pulling power, as we are seeing improved DEF consumption and less slobbering down the exhaust pipes. We will be doing the rest of the fleet in the very near future.
