BMW N47 Intake Manifold Seal Rail - OEM Gasket Carrier for N47N and N47S1

Stop intake leaks and restore crisp diesel performance with this factory BMW intake manifold seal carrier for N47-powered models. This OE sealing frame fits precisely, keeps unmetered air out, stabilises idle, preserves boost, and helps maintain strong torque and economy. Built to BMW spec for perfect alignment and long-term heat and oil resistance.

We run these on our own cars and in customer builds, and the results are consistently excellent. If your N47 has a rough idle, hesitation, whistle, or soot around the plenum, refreshing the intake sealing rail is a proven fix that brings your engine back to its best.
