Introducing the Vader Solutions Fuel System Upgrade for S58 powered M2 M3 and M4's. This uses the same design and engineering that went into developing our popular A90 Supra Fuel System Upgrade. 

This kit is the best solution in terms of fueling, no additional fuel lines required outside of the fuel tank, the stock G Series fuel line is 3/8" already from factory no need to replace that and add a regulator, BMW from factory uses and electronic dampener/regulator combo so this eliminates the need for aftermarket FPR. Super smooth install once the pump is removed and wiring is a breeze. We also DO NOT use zip-ties like the competitors do.

We made it easy for you guys no matter what setup you're running in terms of fuel pump activation. Just let us know what you are going to run and we will ship you a plug n play wiring kit accordingly 

Fuel System upgrade is required over 500-550WHP
