The new R&D Triple Cooling Block is now available, featuring three ½" cooling outlets. Our testing has proven that one ½" line to each cylinder will eliminate engine overheating. When the engine becomes heat soaked, like all GPR's do, the power fades away. The R&D cooling block delivers optimum cooling so the engine will not become heat soaked and will produce maximum power through out it's operating time. The block installs into the stock location and utilizes the stock o-ring to seal. R&D offers optional ½" through hull fittings to ease installation.
