The Trick Flow TFX 83 lb/hr Fuel Injectors are engineered for high-performance fuel systems requiring increased fuel delivery, precise fuel control, and dependable operation. Featuring electronically machined disc-type fuel control valves, improved nozzle technology, and optimized coil windings, these injectors are designed to deliver consistent fuel atomization, reduced operating noise, and improved resistance to clogging.
Constructed with low-magnetic stainless steel components for corrosion resistance, the TFX series incorporates high-quality Viton O-rings, OEM-style retaining grooves, and precision filtration to help ensure reliable operation under demanding conditions.
Each injector is tested at a 100% duty cycle to verify reliability and performance. Featuring a 2.2-ohm low-impedance design, these injectors require a compatible 4/1A peak-and-hold injector driver, making them suitable for properly configured high-horsepower naturally aspirated and forced-induction applications.
Sold as a complete set of eight injectors.

The Trick Flow TFX series utilizes precision disc-type fuel control technology designed to promote consistent atomization while reducing susceptibility to contamination and clogging.
Its stainless steel construction helps resist corrosion, while Viton sealing components provide dependable sealing between the injector, fuel rail, and intake manifold.
Integrated 0.5-micron filtration helps prevent foreign particles from entering the injector, supporting consistent fuel delivery and long-term reliability.
Important: These are low-impedance fuel injectors with a 2.2-ohm coil resistance.
The injectors require an engine management system or compatible injector driver designed for 4/1A peak-and-hold operation.
They should not be connected directly to an ECU designed exclusively for high-impedance injectors unless an appropriate driver solution is used.
All published flow ratings are based on a 3-bar (43.5 PSI) fuel pressure differential.
ECU tuning and injector calibration may be required.
Verify electrical compatibility, injector dimensions, and fuel rail fitment before ordering.
Fuel compatibility should be verified for the intended fuel type and application.
Sold as a complete set of eight injectors.
