RB BMW N54 PCV Valve Screw‑On Cap for 1M, 135i, 335i, 535i and Z4 35i
Upgrade your BMW N54 crankcase ventilation with the RB BMW N54 PCV Valve Screw‑On Cap. This RB PCV screw‑on cap replaces the brittle factory plastic cap on the N54 valve cover and is the ideal companion to the RB BMW N54 PCV Valve upgrade. Designed for reliability on the N54 twin turbo engine, it helps avoid costly valve cover replacement when the OEM cap cracks, and delivers a clean, secure seal for consistent PCV system performance.
We run this part on our own N54 cars and customer builds, and it has proven to be a simple, dependable solution. Nforcd customers love the fit, finish and peace of mind it brings to tuned and stock N54 engines alike.
Why choose the RB PCV Screw‑On Cap for your N54
- Direct replacement screw‑on cap for the BMW N54 PCV location on the valve cover.
- Robust design that will not crack like the fragile OEM plastic piece can.
- Pre‑equipped with a new O‑ring for a tight, reliable seal.
- Great pairing with the RB BMW N54 PCV Valve for a complete N54 PCV upgrade.
- Cost‑effective fix that avoids buying a full valve cover just to replace the cap.
Installation notes
- Includes a new O‑ring. Lightly coat the O‑ring with clean engine oil before threading into place.
- Do not over‑tighten. Over‑tightening can damage your valve cover.
