Key Performance Benefits

The "FTP" (Full Tilt Performance) design is engineered to overcome common stock manifold failures like cracking or leaking while boosting overall efficiency.

• Increased Airflow: Provides roughly 18% more airflow than stock, which helps the turbo spool faster and reduces lag.

• Cooler Temperatures: The ceramic coating helps lower Exhaust Gas Temperatures (EGTs) by 80–100°F and under-hood temperatures by up to 300°F.

• Efficiency Gains: Users typically see an increase of 28–32 horsepower and an improvement in fuel economy of 0.2 to 0.3 MPG.

• Durability: Features thicker manifold flanges and walls to prevent warping and cracking over time.
