The MINI Cooper S engine utilizes a turbocharger to pressurize the intake tract to force-feed the engine air to produce power. As such, NM Engineering has identified a weak point that impairs the efficiency of this system.The NM Engineering Hi-Flo Air Charge Pipe replaces the factory necked-down hose between the intercooler and throttle body (cold-side) with a new pipe and silicone couplers that will not expand under boost. The system eliminates the OEM sound chamber which results in increased turbo response as well as mid-range and top-end power.
