This is achieved through elimination of the most critical restriction in the entire intake system, the turbocharger inlet pipe. Because of this restriction, no intake airbox / filter design can physically match the gains achieved by upgrading to the APR Turbo Inlet System alone. This is the first step one should take when upgrading their intake system and paves the way for even more gains. Read More

The ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port once the ECU is unlocked, resulting in a clean and headache-free install.
