The FX-350 delivers fuel at 35 MPa (350 bar) versus 25 MPa on the FX-200, adds about 90% more flow than stock and lets your injectors flow up to 40% more fuel before they hit the injection window limit. The higher pressure also atomizes fuel better for a more complete burn.\u003c\/p\u003e\u003ch2\u003eFits\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eMercedes-AMG GT, GT S, GT C and GT R (M178)\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 all install 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\u003eSpool 10-micron filter\u003c\/h2\u003e\u003cp\u003eThe included filter unit protects the high pressure pumps and injectors from debris without a noticeable pressure drop on the low side.\u003c\/p\u003e\u003ch2\u003eGood to know\u003c\/h2\u003e\u003cp\u003eChoose at checkout whether to add the ethanol analyzer or use one you already have.
