Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

Flow Bench

The APR Intake system dramatically out performs the factory intake system and improves upon the closed box design. As performance increases, so does the importance of a high-flow high-quality intake system as a large pressure drop forms between the factory intake’s inlet and outlet. As listed in the chart every combination of APR Intake Systems and throttle body pipes dramatically outflows their stock counterparts. The APR Open Intake System with APR Ultracharger is roughly 35% less restrictive compared to the factory intake at 28" of H2O. By allowing the engine to breathe, the intake system lowers the intake air temperature, and allows for performance gains upwards of 17 AWHP at Stage 2+ (93). As performance climbs further, so does the power gain seen with the APR Intake system!
