BMW B58 TU / Supra High-Pressure Fuel Pump Upgrade Retrofit
– Genuine BMW # 13518631642 HPFP
If you are looking to make more than around 450WHP on your B58 GEN 1 powered BMW the factory HPFP is going to become the weak link at those levels. This will give you much-increased headroom for making power. This upgrade is good for around 600HP on gasoline.
