When HSP Diesel wanted to design a new VGT Intake Mouthpiece we decided to look at what we thought were issues and overall restrictions of the factory piece. We knew that in order to get the transition we wanted from the turbo to the intake we would have to make these by hand. We needed to put a personal touch on them so we could have a free and better flowing design. But this had a few wrenches were thrown into the mix we needed to be able to retain the factory location we needed this VGT Intake Mouthpiece to work with as many intakes as possible. Once we had our location down and the hand fabrication side taken care of we wanted to add in an o-ring style seal. This made it so the inlet of the turbo was so well sealed it eliminated the unfiltered air entering the turbo.

Increased airflow means more power, more power means better performance and driveability. All of this together means you will likely experience an increased fuel efficiency and let’s not forget this HSP VGT Intake Mouthpiece makes that turbo sound so much better.
