Original BMW Intake Valve Collet, 5 mm, for BMW 1–8 Series, X1, X3, X4, X5, X6, Z4, and Mini (2006–2025)

Valve collets are the small split keepers that lock a valve spring retainer into the groove on a valve stem, and Original BMW collet 11-34-1-438-142 does that job on the intake side of a wide range of BMW and Mini engines built from 2006–2025. BMW specifies it at D=5 and a weight of 1 gram. Production started in September 2004, and the collet is made in Germany. It is sold individually. Collets work in halves around the stem groove, so a cylinder head job calls for them in quantity rather than one at a time.

Original BMW Parts include a 24-month parts warranty.
