SPOOL FX-170 N20 N26 UPGRADED HIGH PRESSURE PUMP KIT SP-FX-170-N20

Spool Performance FX-170 High-pressure fuel pump upgrade

What is the FX-170?

The FX-170 is an upgraded high-pressure fuel pump. 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.

Why do you need it

The stock HPFP on the N20 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.

What does the kit include?

1 x FX-170 upgraded high-pressure fuel pumps

Upgraded Fuel lines and all necessary install hardware

Optional:

Ethanol Content Monitor kit with mobile app

Bosch spec 10-micron high flow Fuel Filter

Spool 10-micron filter unit

Our 10-micron filter unit boasts the best filtration available in the market without any noticeable pressure drop in the low side fuel system. The filter unit helps keep the high-pressure pump and injectors safe by protecting them against debris and is highly recommended.

Are tune changes required?

The upgraded pumps do require calibration changes. It is important to apply these changes prior to starting the car with pumps installed to avoid any possible damage and void of warranty. 

Spool Performance can provide calibration details to your existing tuner and/or help you connect with established tuners who are experienced with these pumps. 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.

Low Pressure Fuel Pump Upgrade:

Proper 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.
