Features & Highlights

• 112mm CNC-machined billet aluminum body – precision-cut from 6061-T6 for strength, durability, and flow

• Direct-fit application: Built for LT1, LT4, and LT5 engines, it drops in using your existing OEM six-pin connector—no grafting or guesswork

• Boost-rated – engineered to handle up to 25 psi (draw-through or blow-through setups)

• Complete install kit – includes gasket and mounting bolts for a hassle-free install

• Compatible with LT1, LT4, LT5 engines – ideal for C7 Corvette, Camaro SS/ZL1, CTS-V, trucks & swaps

Why It Matters

• More power, faster – Larger bore = more airflow = more horsepower potential

• No throttle lag – Improved response and drive feel, especially under load or boost

• Built to last – High-torque motor and robust electronics resist boost creep and flutter

Important Notes

• TUNE MAY BE REQUIRED to ensure proper idle, drivability, and to unlock full performance
