Thank you. You have rated this product.
Thickness: 0.8mm (0.2mm LESS than factory thickness)
***Increases compression ratio by 0.13 when compared to a factory head gasket with 83mm bore and 1.0mm thickness. So on an otherwise stock engine which would normally have 8.86:1 compression ratio, with this head gasket it will increase to 8.99:1. If you want to keep the compression ratio the same as OEM, go to our separate listing for the 1.0mm thickness version.
Features precision water/oil route seals and premium grade materials and coatings
