Product Description

These stainless steel intake valves for the M30 are swirl-polished and slightly back cut – we find them reliable and have seen a slight performance advantage over the factory valves and at a great price. Standard 46mm size will be available again soon.

OPTIONAL OVERSIZE: These 47mm stainless steel intake valves are +1mm for the pre-1989 M30 engines (and the correct size for post ’88 E34 engines). Valves are swirl-polished and slightly back cut. Note: The factory seats do not need to be changed when using +1mm oversize valves (but they do need to be cut). These oversize valves are ideal for port & polished performance/race prepped cylinder heads.
