The Trick Flow TFX 30 lb/hr Fuel Injectors are engineered to deliver precise fuel control, consistent atomization, and reliable performance for street and high-performance engine applications. Featuring electronically machined disc-type fuel control valves, improved nozzle technology, and optimized coil windings, these injectors are designed for efficient fuel delivery, 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 dependable operation under demanding conditions.
Each injector is tested at a 100% duty cycle to verify reliability and performance. Featuring a 14.4-ohm high-impedance design, these injectors operate with compatible 12V saturated injector drivers, making them suitable for properly configured factory and aftermarket EFI systems.
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.
These injectors feature a 14.4-ohm high-impedance coil designed for operation with compatible 12V saturated injector driver circuits.
The Jetronic / Minitimer electrical connection is commonly used in older factory and aftermarket EFI applications. Verify connector compatibility and ECU calibration requirements before installation.
All published flow ratings are based on a 3-bar (43.5 PSI) fuel pressure differential.
ECU tuning or injector calibration may be required.
Verify injector dimensions, electrical compatibility, and fuel rail fitment before ordering.
Fuel compatibility should be verified for the intended application.
Sold as a complete set of eight injectors.
