EKP Compatibility Notice

Upgraded pumps draw more current than stock, so if you're on a weak or aged EKP2, it may overheat and shut down. We recommend upgrading to an EKP3.

Installation Notes

European spec vehicles: The original top hat may need to be transferred over during installation.

Required tool: A fuel pump lock ring removal tool is required for installation. Our Fuel Pump Lock Ring Removal Tool for BMW E-Chassis and MINI is available separately - add it to your order from our store.

Stepped up from a 450 setup when I added meth, and the 535 was the right call. Pressure stays rock solid even at the top of third gear, and the bucket assembly feels well engineered. Three months in with no issues to report.
