Eventuri Mini JCW GP3 / Clubman / JCW 306HP Carbon IntakeFitment: 306hp F56 JCW GP3 and 306hp F54 JCW Clubman The F5X JCW Eventuri intake system is a perfect example of our "Complete System" principal. It is a sealed system which ensures that the turbo does not draw hot air from the engine bay but enhanced with a functional bonnet scoop which forces ambient air into the intake duct. This duct has a larger internal volume than the stock version and also draws air from the stock location above the radiator.
