Performance inlet valve to fit 2000 engines. 45mm diameter head - 1mm larger than standard. 9mm (standard) valve stem diameter. The valve is also made fractionally longer than standard to allow for the larger diameter head  thus ensuring the spring retainer is still in the correct place - a design feature sadly lacking on most 1mm oversize valves on the market! Made from high quality steel (1.4718) with excellent tensile strength.

Price is per valve
