4.8/5.3/6.0 ('99-'06) Truck Motors Fuel Injector Clinic Injector Set: 8x1200cc/min (110lbs/hr) at 3 bar (43.5psi) fuel pressure and 130lbs/hr (1350cc/min) at OE 58psi (4 bar) fuel pressure. Saturated / High Impedance Injectors. Includes Pigtails PGTJETR8 or add PADPJtoGM8. These injectors utilize the latest technology and provide great linearity and short pulse width repeatability. Plug and Play GM ECU Data available on our website. PREVIOUSLY IS304-1100H.

This injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and the results are provided on the Data Match Sheet providing the most complete flow matching and latency value information available in the industry today.

Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 90deg F fuel temperature using CF-16B calibration fluid.

Superior short pulse width control and state of the art matching make these injectors easy to tune and provide great drivability.

Fuel Injector Clinic injectors are set up to and include all o-rings needed to fit the factory application for the listed vehicle. If you are using aftermarket or other unusual setups please contact us prior to placing your order to make sure you receive injectors that fit properly.

Every injector is covered against failure caused by defects in original manufacture by our lifetime warranty.

This set of injectors requires you to change the injector plug on the wiring harness in your car. This can be done by soldering in the pigtails (included with purchase) to replace the plugs currently on your harness, or you can choose to purchase the optional plug-n-play adaptors which will convert from the type of plugs on these injectors to the plugs on your harness without any need for cutting or soldering.

This plug conversion is made necessary because FIC always chooses to provide brand new, unused injectors for its performance applications. We do not believe that increasing the chance of a failure due to using remanufactured or core program based injectors is ever warranted.

Very nice
Size: Large, Color: (100) White / White / Pitch Gray
I just received these for my son. They are very nice and look sturdy, but he hasn't worn them yet, so I cannot speak to how well they hold up in the wash or when worn. They appear to be the right size and look stretchy, but not the kind of stretchy that feels super tight on the foot (which I don't like). If they wear unusually well or poorly, I will come back and edit this.
