The Supertech oversize intake and exhaust valve guide for Mini R56 is a single replacement part offered as a drop-ship item to support oversized stems and tighter valve-to-guide control. Use this guide during head rebuilds or valve servicing where increased guide diameter is needed to maintain proper clearance and consistent valve operation in R56 applications.
