{"product_id":"4g63-86-5mm-bore-x-1-8mm-thickness-head-gasket","title":"4G63 86.5mm Bore x 1.8mm Thickness Head Gasket","description":"The Tomei 86.5mm bore head gasket, with a 1.8mm thickness, is engineered for the 4G63 engine found in Mitsubishi Evolution IV through IX models (1996-2004). Its construction features thicker bore seals to effectively contain pressurized gases within the combustion chamber.\n\nTomei gaskets are constructed using premium-grade materials, including stainless steel, and unique rubber coatings on both the top and bottom layers. This specialized coating strengthens the seal and enhances contact with the head and block surfaces. The stainless steel provides strength and heat resistance, efficiently transferring heat away from the combustion chamber to the cylinder block, while its inherent flexibility helps prevent blown gaskets and damage to the cylinder block. The gasket also incorporates precision water and oil route seals to maintain steady circulation of engine fluids.\n\nThis head gasket is specifically constructed for the 4G63 engine to ensure optimal performance with minimal stress on the block and head. It offers extremely durable combustion chamber seals capable of enduring high power, boost, and temperature conditions. Multiple thickness choices are available for compression ratio adjustment, with this specific part number (TA4070-MT01D) being 1.8mm thick.","brand":"Tomei","offers":[{"title":"Default Title","offer_id":52873024110904,"sku":"TA4070-MT01D","price":108.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4g63-86-5mm-bore-x-1-8mm-thickness-head-gasket","provider":"MOTORMIA","version":"1.0","type":"link"}
