Using a block guard on your engine turns your open deck into semi-closed deck. Block guards strengthen the block by reducing wobble in the cylinder walls. They are a must for boost and high rpm motors. Our block guards are CNC milled from aircraft grade 6061 aluminum and finished in an anodized coating for better corrosion resistance. They also feature machined coolant passages that promote critical coolant flow, especially where the cylinders join. Other brand block guards may create destructive hotspots around cylinders, and increase the chances of engine failure caused by overheating. Our block guards are machined to be slightly over sized to compensate for the cylinder walk flaw common in open-block designs, and to ensure a water tight seal around each cylinder when pressed in your block. They are made in the United States. For Honda 1.8L B18 and 1.6L B16 engines.
