Part # 003-HSP-COLOR

The HSP VGT Intake Mouthpiece is perfect for anyone looking to increase the performance and look of your engine bay. Our mouthpieces are designed to outperform the factory units by increasing the volume. The aluminum casting allows the creation of the complex shape required to direct the air as efficiently as possible to the turbo charger. This turbo inlet will fit all stock appearing/drop-in aftermarket turbo chargers. Don't be let down by the substandard, knock-off turbo inlets in today's market. Invest in the high quality and standards of HSP Diesel. Our mouthpiece paired with the PCV reroute add-on (MA-10040) will not require the mouthpiece plug or resonator plug.
