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 C63 \/ C63 S (M177)\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 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, use one you already have, or skip it. The pump needs calibration changes, and they must be applied before the car is started with the pump installed. A custom tune is needed to get the full output. Spool supplies hardware, not tunes, but can share calibration details with your tuner. Adequate low pressure fueling is critical for the pump and injectors, so plan an upgraded low pressure fuel pump into the build. Professional installation is recommended.\u003c\/p\u003e","brand":"Spool Performance","offers":[{"title":"Yes Include the Spool Ethanol Content Analyzer","offer_id":46564604805205,"sku":"SP-FX-M177-C63","price":7349.99,"currency_code":"USD","in_stock":true},{"title":"I have an existing Spool Ethanol Content Analyzer","offer_id":46564604837973,"sku":"SP-FX-M177-C63-EE-45MH","price":6999.99,"currency_code":"USD","in_stock":true},{"title":"I would not be installing an Ethanol Content Analyzer","offer_id":46564604870741,"sku":"SP-FX-M177-C63-EE-45HJ","price":6999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/9769\/8389\/files\/FX350-1-1014x912_0f9b2303-f4ea-40e6-8683-8254c6d1b57f.jpg?v=1793251116","url":"https:\/\/www.wrenchhaususa.com\/products\/mercedes-amg-c63-spool-fx-350-high-pressure-fuel-p","provider":"Wrench Haus","version":"1.0","type":"link"}
