With electronically drilled and machined disc-type fuel control valves, plus improved nozzles and coil windings, Trick Flow TFX™ fuel injectors atomize fuel better, resist clogging, are quieter, and require less energy to operate than other aftermarket injectors. The features don’t stop there. Low magnetic stainless steel injector bodies prevent corrosion from underhood contaminates and seal the injectors from moisture contamination. OEM-style clip grooves secure the injectors to fuel rails and eliminate possible fuel leaks. Viton® fluoroelastomer O-rings seal the injectors to the fuel rails and intake manifold to prevent fuel and air leaks under extreme operating conditions. High-quality, 1/2 micron filter screens keep foreign debris and contaminants from entering the injectors to ensure proper performance and a long life cycle. TFX fuel injectors are 100% duty cycle tested to ensure reliability and performance. All flow values are at 3 bar (43.5 psi).
