This is one of the strongest, most efficient heat sink heads available. This innovative design has been tested for the optimum heat dissipation, size and strength. This high strength 7075 aircraft aluminum heat sink head will keep you engine running cool in the most demanding conditions.
The head clearance for the glow plug access is reduced for maximum cooling characteristics. This heat sink head is the same diameter of the standard 2.5 head but much taller. This minimizes aftermarket part clearance problems normally found when upgrading with other aftermarket heads. Heads can be upgraded to the patented Heat Exchanger Cooling System.
