Dorch Engineering B58 Gen2 DS25 HPFP Upgrade

OVERVIEW

From the creators of the world's first B58 direct-injection fueling upgrades comes the next generation of pumps: the 350-bar version of the wildly successful DS25, another first of its kind in the aftermarket. Internally, the entire pump body, spring rates, and plunger depth have been reworked, fully optimizing volumetric efficiency for 350 bar operating pressures on Gen2 B58 (B58TU). No cutting, no bending, no crimping — this kit drops right in with full control from the DME, just like the OEM pump.
