Proflow's fabricated aluminium intake manifold kits provide excellent mid range torque whilst dramatically improving top end power and is ideal for anyone looking to build an ultra responsive street or drag car. The 90mm universal throttle body seals with an o-ring and will bolt to any vehicle that was running a mechanical throttle body beforehand, using the supplied cable bracket. With a heavy duty billet flange, this manifold will perform best with any upgraded turbo packages and other aftermarket bolt ons. This kit comes complete with a 17mm ID fuel rail, fittings and all necessary hardware for mounting. It also includes a radiator hose kit and water-neck relocation kit which allows the remote mounting of the water neck to clear the throttle body. Suits a short length 14mm o-ring injector. Some modifications may be required for fitment. Wil suit the following vehicles with RB25 engines: For Nissan Skyline R32 For Nissan Skyline R33 For Nissan Skyline R34 (Non-neo)
