WE STRONGLY RECOMMEND using the WCFab open flange style intake horn with this turbo (2017-19 Year WCF100332; 2020-21 Year WCF100326). Our standard horn with MAP ring will suffice but the turbo is more efficient and produces more horsepower with the open style flange VS MAP ring flange when tested back to back on the dyno. This high flow intake horn (shown in the drop down options) paired with our High Flow Air Intake Kit will Maximize Performance, EGT Control, and Spool up.
WE STRONGLY ADVISE AGAINST using the OEM intake horn with this turbo! The OEM horn Limits air flow by ~30% verses the high flow horn and the turbo will not perform at its maximum potential.
Stealth 67G2 VGT - L5P 750 rear wheel horsepower capable the Stealth 67G2 VGT is an easy to install upgrade that spools up quickly, controls EGT's under heavy load, allows to turbine braking during towing scenarios, and kicks ass when leaned on.

The L5P Stealth 67G2 features the largest turbine and vanes available in this frame. Increasing turbine size dramatically reduces drive pressure under heavy load, helping you achieve nearly a 1:1 drive to boost ratio under most operating conditions. Controlling drive pressure helps make more power and significantly lowers EGT's.
