Flow Bench Testing

The Dinan Intake System out performs the factory intake and improves upon the factory paper filters by using our own drop-in high flow filters. The Dinan Intake System flows nearly 20% more air as a result compared to the factory intake.. By allowing the engine to breathe, the intake system lowers the intake air temperature, and allows for performance gains upwards of 7 WHP on a completely stock vehicle.
