Performance Diesel Inc. (PDI) Big Boss Intake manifolds are built to increase and balance the air going into the engine. By opening up the manifold in key areas, airflow will increase up to 35% leading to lower air intake temperatures and resulting in power gains of up to 20 Horsepower. These direct replacement manifolds are simple to install and utilize factory hardware.
PDI uses only the best material for their intake manifolds. Like all PDI products, this manifold is designed to make more horsepower and create more efficiency so you save money while making the drive more enjoyable.
