With a gap in the market for a high-flow inlet plenum, we desinged this based upon a tried-and-tested style that's guaranteed to see results. \n \nMade from cast aluminium and featuring a unique trumpet design to encourage airflow, the plenum improves throttle response, power and torque at any level of tune, from standard to big power. \n \nAvailable in a range of colours, the three piece design is a direct replacement for the original and the plenum seals together with an O-ring supplied in the kit, together with all bolts and washers to secure. \n \nThe plenum itself seals to the inlet manifold reusing the Ford O-rings and features take-offs for all vacuum line fittings, as well as the fitment of the original throttle body and O-ring. \n \nDesigned with a purpose to increase BHP & Torque & Better air flow!
