Vauxhall Z20LEH Z20LEL Z20LER Z20LET Thermal THERMOBLOC Inlet Manifold Gasket
Tax included.
Inlet air temperature is always the enemy in performance tuning; heat transfer via conduction from the head is the primary source of heat soak in aluminium inlet manifolds, ThermoBloc is the number one method of massively reducing heat soak and is ideal for all performance vehicles especially race vehicles where there is a period of engine running prior to the start of a race.
These are not just a copy of a gasket this has been drawn in CAD and CNC cut for a perfect fit.
