Show original supplier description
The Tomei Stainless Head Gasket is designed as a high-performance replacement for Mitsubishi 4B11 engines, featuring a bore size of 87.5mm and a thickness of 1.0mm. Constructed from durable stainless steel, this material was selected for its superior heat capacity, which allows for efficient heat dissipation. This characteristic significantly lowers the risk of head gasket failure, especially in high-performance applications. This head gasket offers versatility in engine tuning. By adjusting the head gasket's thickness, the cylinder capacity can be modified. A thicker gasket, like this 1.0mm option, can be used to increase the engine's compression ratio. Conversely, a thinner gasket could be employed to maintain the stock compression ratio. Tomei provides resources, including a Compression Ratio Calculator and Stock Engine Data, to assist users in selecting the appropriate head gasket for their specific build. Each package includes one head gasket, necessary hardware, and installation instructions. Tomei offers a Limited Warranty on this product.
