NRW Design Billet Valve Cover - BMW G80 M3 | G82 | G83 M4 | G87 M2 (S58)

The NRW Design S58 Billet Valve Cover replaces the factory plastic cover with one CNC machined from a single block of 6061 billet aluminium. Rather than a straight copy of the OEM part, it has been re-engineered around the needs of high-performance and high-horsepower S58 builds.

The factory PCV system is removed in favour of an external catch can setup, with two 12-ORB ports and -12AN swivel fittings giving large, robust crankcase ventilation connections. The cover has been proven on S58 builds producing more than 1,600 whp, including some of the fastest S58-powered cars in the world.

Please note: Supplied with the valve cover and 2 x 12-ORB to -12AN swivel fittings in a raw billet finish. The factory PCV system is deleted, so an external catch can system is required – the catch can, hoses, additional fittings and plumbing are sold separately.
