Show original supplier description
The Fuel Injector Clinic FIC-IS303-1200H set includes eight high-impedance, "High-Z" fuel injectors, each with a 1200cc/min flow rate (110 lbs/hr at 43.5 psi). These injectors are designed for specific GM LS engines including LS3, LS7, LSA, L76, L92, and L99. They are E85 compatible and feature a stainless alloy valve construction, making them suitable for various fuel types from pump gasoline to specialized race fuels like Q16. Utilizing Fuel Injector Clinic's proprietary Data Match Technology, each injector is individually serial numbered and flow-matched within the set. The provided Data Match Sheet details flow numbers and latency values, ensuring precise tuning and excellent drivability with superior short pulse width control. These injectors have a height of 38mm, a top O-ring size of 14mm, and an outer diameter of 15mm. Installation requires a change to the factory injector plugs on the wiring harness. This can be accomplished by soldering the included EV1 pigtails or by using optional EV1 to EV6 plug adapters. FIC emphasizes the use of brand-new, unused injectors for performance applications, avoiding potential failures associated with remanufactured components. A lifetime warranty covers against manufacturing defects.
