Description

The Fuel Injector Clinic IS301-0525H is a set of eight high-impedance fuel injectors engineered for LS1 engines. These injectors deliver a precise flow rate of 525cc/min (50 lbs/hr at 3 bar / 43.5psi) and 58 lbs/hr (600cc/min) at OE 58psi (4 bar) fuel pressure. The set is meticulously flow-matched to within 1%, with each injector individually numbered and accompanied by a detailed flow sheet. These injectors feature superior short pulse width control and tight manufacturing tolerances, ensuring great drivability and ease of tuning. They are designed to fit factory applications with included o-rings, and come with PGTUSC8 pigtails for wiring harness adaptation. Alternatively, optional Plug & Play adaptors (PADPUtoJ8) are available to convert without cutting or soldering. Fuel Injector Clinic prioritizes new, unused injectors for performance applications, avoiding the increased risk of failure associated with remanufactured components. Every injector is covered by a lifetime warranty against manufacturing defects.
