NRW-Design BMW S58 Billet Multi Baffled Oil Cap

The NRW Design S58 Billet Multi-Baffled Oil Cap with Swivel Option is a premium performance upgrade designed for high-output BMW S58 engines. Machined from high-quality billet aluminum, this oil cap replaces stock plastic units with a stronger, more durable alternative engineered to perform under demanding conditions.

This multi-baffled design promotes improved crankcase ventilation, minimizing oil blow-by while reducing pressure spikes in the valve cover during aggressive driving or boosted applications. The integrated swivel outlet option allows flexible hose routing and cleaner plumbing for catch cans, vacuum lines, or breather setups.

Finished with precision detail and available in raw aluminum, this oil cap is both functional and visually striking, making it an ideal upgrade for performance builds, track cars, or show vehicles.
