Stop boost leaks and keep your diesel running sweet with this factory-spec air intake sealing ring, part number 11618511416.

If you are chasing a whistle under load, oil haze around the connector, uneven idle or lost performance, this OE ring is the simple, proven remedy that helps recover response, economy and smoothness.

We have fitted this ring on customer cars and our own builds with consistently excellent results. Owners pick the genuine part for exact sizing, correct material hardness and long service life.
