The FX-350 uses a stainless body with a DLC-coated piston and bore, and its plunger springs are designed to work with the Spool high-lift cam lobe mod without floating at high rpm. Paired with Spool IFX150 Gen 2 injectors it is the missing piece for DI-only big power.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eBMW models with the Gen 2 B58 engine\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePump alone: about 800 whp on gasoline, 670 whp on E50, 600 whp on E85\u003c\/li\u003e\n\u003cli\u003eWith IFX150 Gen 2 injectors: about 900 whp gasoline, 740 whp E50, 660 whp E85\u003c\/li\u003e\n\u003cli\u003eWith injectors and the Spool cam lift mod: about 1050 whp gasoline, 950 whp E50, 800 whp E85\u003c\/li\u003e\n\u003cli\u003eStainless construction with DLC-coated piston and bore\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpool FX-350 high pressure fuel pump\u003c\/li\u003e\n\u003cli\u003eMounting bracket\u003c\/li\u003e\n\u003cli\u003ePump alignment tool\u003c\/li\u003e\n\u003cli\u003eTriple-layer low pressure line (nylon over stainless over PTFE)\u003c\/li\u003e\n\u003cli\u003ePlug-and-play HPFP adapter harness\u003c\/li\u003e\n\u003cli\u003eSpool wireless ethanol analyzer kit and 10-micron filter unit (if selected)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eChoose at checkout whether to add the Spool wireless ethanol analyzer kit, reuse one you already have, or skip it, and whether to add the Spool 10-micron filter unit.
