GSC Power Division manganese bronze exhaust valve guide for BMW 335i (E92) inline‑6, +0.001in oversize OD, sold as a single unit. The guide restores the running bore for the exhaust valve stem and matches the specified oversize to fit a reamed head. Constructed from manganese bronze for traditional valve guide service, it provides a durable replacement option where a slight oversize is required to reestablish correct stem clearance.
