1mm Oversize Inlet Valve – 2000 (9mm Stem)

1mm oversize inlet valve, 45mm.

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 and by having 9mm stems also fit in standard valve guides and with standard retainers & collets for the easiest installation for light performance use.
