The pump features a bigger bore size than stock that translates into roughly 50% more flow when compared to stock. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos. The FX170 also is capable of running at 25% more operating pressure than stock pumps helping injectors flow more volume of fuel for the same opening time.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhy do you need it\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe stock HPFP on the S55 Motors is severely limited in capacity when trying to tune and raise the output of the motor. The FX-170 adds 50% more flow to the equation, and also lets the injectors flow more, raising the fueling limits on the platform and helping you run bigger turbos and\/or higher ethanol concentration blends.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpool 10-micron filter unit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOur 10-micron filter unit boasts the best filtration available on the S55 market without any noticeable pressure drop in the low side fuel system.

BLE4.0 allows you to use your regular Bluetooth devices on your mobile devices while being connected to the SPOOL ECA module. Fuel lines used in the kit are braided steel nylon core fuel lines that are 100% E85 compatible.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAre tune changes required?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe upgraded pumps do require calibration changes.

Custom tuning is required to get maximum output out of the upgraded pump setup for your specific vehicle setup and ambient conditions. Spool Performance is a hardware manufacturer and does not provide custom tunes, but can assist with questions your tuner may have.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow Pressure Fuel Pump Upgrade:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProper low pressure fueling is extremely important for proper functioning and durability of the high pressure pumps and injectors in a DI system. Inadequate low pressure fueling can cause damage to the pump piston and bore as they are lubricated by controlled leakage of fuel. Resulting damage from low pressure starvation is detectable and would be cause for voided warranties. Please make sure you plan out your fuel system build with proper low pressure upgrades when necessary.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1272\/9301\/files\/Spool_Performance_BMW_S55_FX-150_High_Pressure_Fuel_Pump_M2_Competition_M3_M4_-5_2048x2048.jpg?v=1632743699\" alt=\"Spool Performance BMW S55 FX-150 High Pressure Fuel Pump (M2 Competition, M3 \u0026amp; M4) - ML Performance UK\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1272\/9301\/files\/Spool_Performance_BMW_S55_FX-150_High_Pressure_Fuel_Pump_M2_Competition_M3_M4_-5_2048x2048.jpg?v=1632743699\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2 x FX-170 upgraded high-pressure fuel pumps\u003c\/li\u003e\n\u003cli\u003e1 x Ethanol Content Monitor kit with mobile app\u003c\/li\u003e\n\u003cli\u003e1 x Bosch spec 10-micron high flow Fuel Filter\u003c\/li\u003e\n\u003cli\u003eUpgraded Fuel lines and all necessary install hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBMW M Series F87 LCI M2 Competition S55 (2018+)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F87 LCI M2 CS S55 (2020+)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F80 M3 Saloon S55 (2012-2015)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F80 LCI M3 Saloon S55 (2015-2018)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F82 M4 Coupe S55 (2013-2017)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F82 M4 GTS Coupe S55 (2013-2017)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F82 LCI M4 Coupe S55 (2016-2019)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F82 LCI M4 CS Coupe S55 (2016-2019)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F83 M4 Convertible S55 (2013-2017)\u003c\/li\u003e\n\u003cli\u003eBMW M Series F83 LCI M4 Convertible S55 (2016-2019)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eCompatibility Check\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
