BMW Valve guides

C630 silicone aluminium nickle bronze BMW valve guides

Manufactured in house as a replacement guide for the originals Our guides are machined to use an optional silicone valve stem seal. While not required for stock use, in performance applications not even a few molecules of oil may be allowed into the combustion chamber. So with that in mind I designed a guide that will do both. Available as eaches, pairs or sets of 4. Specify stock or oversizes when ordering, or send your heads we’re happy to install guides only If you’d like cut the seats yourself.
