Block Off Plate For BMW N54/N55 Engines Oil Thermostat Delete Compatible With 135i 335i 535i Z4
Upgrade your BMW N54/N55 with a precision CNC milled oil thermostat delete plate. This block-off plate replaces the factory oil thermostat on N54/N55 engines, enabling you to run a larger aftermarket oil cooler and thermostat if you desire. Crafted from a solid block of billet T-6061 aluminum, it is anodized and machine engraved for a durable, premium finish that looks as good as it performs.
Designed for BMW N54 and N55 engines, including popular models like the 135i, 335i, 535i, and Z4, this plate helps manage oil temperatures more effectively under demanding driving conditions. By removing the factory thermostat path, it creates a streamlined cooling route that supports cooler oil temps, cleaner engine bays, and a greater potential for upgrade flexibility without sacrificing reliability.
Benefits & Tips
- Lower oil temperatures when paired with a larger aftermarket oil cooler, helping protect engine bearings and maintain consistent performance under high-load driving or track use.
- Cleaner engine bay with a finished, integrated look thanks to the anodized, machine-engraved surface.
- Flexible upgrade path ideal for performance builds where a larger oil cooling setup is desired; supports future cooling upgrades without reworking the thermostat routing.
