Dorch Engineering DS15 HPFP Upgrade for BMW F/G chassis B58

Dorch Engineering presents its next-level DS15 HPFP Upgrade for BMW F/G Chassis B58. Replacing the DS1, the DS15 has been fully redesigned & optimized, featuring an improved hose routing package with no extra cutting, bending, or crimping. Internally, we've altered the pressure chamber, spring rates, and plunger depth for increased volumetric efficiency. Boasting a max of 250 bar capacity, the DS15 can produce up to +30% greater fueling at 200 bar.
