{"product_id":"engineering-high-pressure-fuel-pump-upgrade","title":"Engineering High-Pressure Fuel Pump Upgrade","description":"The Dorch Engineering DE-581-25A represents the next generation of B58 direct-injection fueling upgrades, building upon the success of their previous DS2 pump. This \"Stage 2.5\" HPFP has been entirely re-engineered, featuring a reworked pressure chamber, updated spring rates, and an optimized plunger depth to maximize volumetric efficiency.\n\nThe design prioritizes a 100% plug-and-play installation with exact OEM hose routing, meaning no cutting, bending, or crimping is required. This ensures zero interference when accessing coil packs or spark plugs. The kit includes a 250 bar capacity hardline for a simple connection to the fuel rail, maintaining full DME control just like the factory unit. Performance-wise, the DS25 supports up to 750whp on gasoline and 550whp on E85, with an optional +40% cam upgrade boosting these figures to 1000whp on gasoline and 770whp on E85.\n\nDorch Engineering backs this upgrade with a lifetime warranty, underscoring the pump's reliability. They also provide extensive customer and tuning support, with in-house engineers and calibration specialists available to assist. The kit contains the HPFP with hardware, a high-pressure line, a quick-connect low-pressure line, a low-pressure line bracket, and a plug-and-play adapter harness.\n\nThis kit is specifically designed for Gen 1 B58 vehicles, including models like the F20\/21 140i\/140xi, F22\/23 240i\/240xi, F30\/31\/34 340i\/340xi, F32\/33\/36 440i\/440xi, and select G-series models (G30\/31 540i\/540xi, G32 640i\/640xi, G11\/12 740i\/740xi, G01 X3 m40i, G02 X4 m40i) only up to the 2019 model year. It is NOT compatible with Gen2 B58 vehicles.","brand":"Dorch","offers":[{"title":"Default Title","offer_id":52687725461816,"sku":"DE-581-25A","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687896586.webp?v=1784886561","url":"https:\/\/store.motormia.co\/products\/engineering-high-pressure-fuel-pump-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
