Product Information
1mm oversize inlet valve, 42.5mm.
Manufactured from a close limit one piece electrically upset 214N austenitic stainless steel forging with a Stellite 12 hard tip, machined all over with a pulse plasma nitride treatment on the valve.
This is the largest valve that will fit in a standard valve seat, by having 9mm stems also fit in standard valve guides and with standard retainers & collets for the easiest installation for light performance use.
This part is a direct replacement for standard items with no other modifications being required.
