BMW N54 Twin-Turbo Engine Billet Aluminum PCV Valve Cap Cover Replacement Kit for E82 / E88 / E90 / E91 / E92 / E93 / E60 / E61 / E71 / E89 / F01 / F02 (2005 - 2016)

Permanently solve the BMW N54 PCV valve cap failure with this premium billet aluminum replacement kit, precision CNC-machined from 6061-T6 aircraft-grade aluminum for permanent durability and reliable crankcase ventilation system sealing. The factory plastic PCV valve cap on N54 twin-turbo engines is a notorious failure point — over time the plastic becomes brittle from heat cycling, develops cracks, and breaks down entirely, allowing crankcase pressurization, oil loss, vacuum leaks, and the rough idle and lean fuel codes that frustrate N54 owners. This billet aluminum replacement permanently solves the problem with rigid metal construction that won't crack, deform, or degrade under sustained heat exposure. Paired with a heat-resistant fluoroelastomer O-ring for superior sealing, the kit properly routes crankcase gases back into the combustion chamber as designed, preventing crankcase pressurization and oil loss issues common to aged factory PCV systems.

Features:

• Premium 6061-T6 billet aluminum construction – aircraft-grade aluminum permanently eliminates the cracking and brittleness failure mode of the factory plastic PCV cap

• Heat-resistant fluoroelastomer O-ring – delivers superior heat and chemical resistance compared to standard NBR rubber seals, preventing leakage at sustained engine operating temperatures

• Direct factory replacement design – manufactured to OE specifications for clean, modification-free installation in the factory PCV valve location

• CNC machined precision – uses latest-generation CNC technology to ensure high dimensional accuracy and perfect OE-grade fitment

• Anodized surface finish – delivers corrosion resistance and a sleek motorsport-grade aesthetic for long-term engine bay durability

• Proper crankcase ventilation routing – channels crankcase gases back into the combustion chamber as designed, preventing pressurization and oil loss

• Wide N54 chassis compatibility – fits the entire BMW N54 twin-turbo engine lineup across 1, 3, 5, 7 Series and X6, Z4 chassis
