The FX-350 uses a bigger bore for about 90% more flow than stock and runs up to 35 MPa (350 bar) versus 25 MPa on the FX-200, which lets the injectors flow up to 40% more fuel with shorter injection times and better atomization. It is fully E85 compatible and plug and play, with no cutting or splicing.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eAudi RS6 Avant (C8, EA825 4.0T V8)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eWhat's included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e2 x Spool FX-350 upgraded high pressure fuel pumps\u003c\/li\u003e\n\u003cli\u003eBosch-spec 10-micron high-flow fuel filter\u003c\/li\u003e\n\u003cli\u003eUpgraded fuel lines and installation hardware\u003c\/li\u003e\n\u003cli\u003eSpool wireless ethanol content analyzer kit with phone app (if selected)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eChoose at checkout whether to add the ethanol analyzer, use one you already have, or skip it.
