S58 Billet Valve Cover G80/G82

NRW Design S58 Billet Valve Cover – Precision CNC-Machined from 6061 Aluminum

Upgrade your BMW S58 engine with the industry’s first fully CNC-machined billet aluminum valve cover – engineered for performance, durability, and style.

Introducing the NRW Design S58 Billet Valve Cover, a premium performance part precision-machined from a solid block of aerospace-grade 6061 billet aluminum. After over a year of intensive design, development, and real-world testing, NRW Design is proud to release this revolutionary upgrade for the BMW S58 engine platform.

Designed as a high-performance solution to replace the failure-prone factory plastic valve cover, our billet alternative eliminates common issues like cracking and oil leaks. Unlike OEM replacements, which simply repeat the same problems, this high-performance valve cover offers enhanced reliability, style, and functionality.

Key Features:

• CNC-machined 6061 billet aluminum construction – unmatched strength and heat resistance

• Direct replacement for the OEM BMW S58 valve cover (Note: PCV system is deleted, engine cover is no longer usable)

• Eliminates factory PCV system – compatible with aftermarket oil catch can setups (plumbing sold separately)

• Dual 10ORB to AN fittings pre-installed for seamless integration

• Track-tested and street-proven – used on NRW's in-house development vehicles

• Custom anodized color options available soon – request your preferred finish at checkout

This is a performance-focused modification and is not compatible with the OEM plastic engine cover due to the PCV delete. A catch can setup is required and sold separately (available as an option with our NRW Single Turbo Kit).
