The FX-350 uses stainless steel construction with a high-tolerance DLC-coated piston and bore, and its plunger springs are matched to Spool's Gen 2 high lift cam lobe mod to limit float at high rpm. Paired with Spool IFX350 Gen 2 DI injectors, it covers the high pressure side.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBMW Gen 2 B46\u003c\/li\u003e\n\u003cli\u003eBMW Gen 2 B48\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 10-micron filter unit (if selected)\u003c\/li\u003e\n\u003cli\u003eSpool wireless ethanol analyzer kit (if selected)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eChoose at checkout whether to add the wireless ethanol analyzer, use the Spool analyzer you already have, or skip it, and whether to add the 10-micron filter unit.
