Aluminum intake plenum. Porsche 997 3.8L DFI IPD

Porsche's new DFI (Direct Fuel Injection) intake tract is a completely redesigned intake system that provides improved performance, fuel economy, and emissions by optimizing the air-fuel mixture directly in the combustion chamber. The DFI Porsche engine package is a finely tuned performance machine, and finding additional power has proven difficult. The unique design of Porsche's new DFI intake system presented very challenging tuning hurdles, but IPD once again developed a design that surpasses the performance of the factory intake system without compromising reliability and drivability. Manufacturer: IPD.
