B58TU High-Pressure Fuel Pump Retrofit for BMW N55 – EWG Only
Upgrade the fuelling capability of your BMW N55 with our B58TU High-Pressure Fuel Pump retrofit.
The factory N55 HPFP can become a limiting factor once power levels are increased. The B58TU pump offers significantly greater fuel flow, making it an ideal upgrade for higher-power N55 builds and setups running increased boost or ethanol blends.
With the correct supporting modifications and custom tuning, this upgrade can support up to approximately 550bhp, depending on the vehicle, fuel quality and overall specification.
A custom ECU calibration is required after installation to correctly utilise the increased fuelling capacity. We offer full in-house dyno tuning specifically for this conversion.
Available Options
Supplied & Fitted In-House (Fitted at Pinnacle Tuning) : We supply the B58TU HPFP, carry out the required N55 conversion and install it at our workshop.
Supplied – Ready to Fit (Posted Option) : The pump is supplied already adapted for the N55 engine and ready for installation.
Please note that the advertised supplied price is for UK customers only.
We can also ship converted pumps to Europe and the USA, however international customers will need to contact us directly for an accurate shipping price before ordering.
