12V VR6 Steel Gasket / Spacer

Lower Compression with our steel headspacer/gasket. When boosting a VR6 engine it is a must to lower static compression. This is easily done with a headspacer/gasket. Most VW engines can handle boost very well if they do not see any detonation. Lowering static compression is the easiest way to prevent detonation. When turbo charging or supercharging a VR6 engine it is a must to lower static compression. This is easily done with a headspacer. Most cars that run pump gas (94 octane or lower) are best with 8.7:1 compression with boost over a 1 bar (15psi). This three layer gasket comes complete with a steel spacer and a mk4 VR6 head gasket ½ on each side. All spacers good for bores up to 83.5mm Spacer sizes: .030” -Corrado/MK3 this will keep compression at 10:1 with stock piston -Mk4 this will lower compression to 9.7:1 with stock piston .060” -Corrado/MK3 this will lower compression at 9.2:1 with stock piston -Mk4 this will lower compression to 9.5:1 with stock piston .100” -Corrado/MK3 this will lower compression at 8.7:1 with stock piston -Mk4 this will lower compression to 9.2:1 with stock piston
