IS140-1440H 1440cc High-Impedance Fuel Injector Set

The Fuel Injector Clinic IS140-1440H is a set of four 1440cc saturated, high-impedance fuel injectors designed for Scion tC/xB, Toyota Matrix, Corolla XRS, and other 1ZZ engines in MR2-S and Celica applications. These injectors feature a stainless alloy valve construction, making them compatible with a wide range of fuels including pump gasoline, E85, Q16, VP Import, and other MTBE oxygenated race fuels. They are flow-tested and rated at 43.5psi (3Bar) at 90°F fuel temperature. Utilizing advanced injector technology and Fuel Injector Clinic's proprietary Data Match Technology, each injector is precisely matched and individually serial-numbered. The provided Data Match Sheet offers comprehensive flow matching and latency value information. This set requires a change to the injector plug on the vehicle's wiring harness. Options include soldering in the included PGTUSC4 pigtails or purchasing optional PADPUtoT4 plug-and-play adapters. Fuel Injector Clinic ensures all o-rings needed for factory application fitment are included. Every injector is backed by a lifetime warranty against manufacturing defects. This set of 1440cc injectors is noted as being compatible with all race fuels and offers excellent idle performance in street-driven cars, while still providing enough fuel to support higher horsepower output on both E85 and gasoline. However, one user reported that these injectors may be too large for pump gas applications.
