4.8/5.3/6.0 ('99-'06) Truck Motors Fuel Injector Clinic Injector Set: 8x1650cc/min (160lbs/hr) at 3 bar (43.5psi) fuel pressure and 180lbs/hr (1900cc/min) at OE 58psi (4 bar) fuel pressure.

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.

Fuel Injector Clinic’s 1650cc/min high impedance injector is the largest high impedance injector compatible with all race fuels and has excellent idle performance in street driven cars while still providing enough fuel to support higher horsepower output on both E85 and gasoline.

The 1650cc high impedance injector can be used with any fuel type based on the stainless alloy valve construction. It is compatible with pump gasoline, E85, Q16, VP Import, FTW and other MTBE oxygenated race fuels!

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.

Not for labrador chewing.
Size: One Size, Style: Stick, Size: One Size, Style: Stick
Not recommended for a Labrador if they enjoy retrieving then chewing, because the stick will only last 20-30mins. The stick does float, and is hollow which is good when it’s been bitten down to ball size.

Great toy except the stitching
Size: Large, Style: Duck Slingshot, Size: Large, Style: Duck Slingshot
Excellent toy. My Lab immediately loved it and I used it to get her to swim for the first time! However, after just one use, the stitching started coming apart under the head. I wish it had been more durable, my dog loves it.

My dogs love these.
Size: One Size, Style: Stick
My dogs are chewers and we use these for the dogs to chase them into the lake. They float well and are easy to see. Even if they start to chew on them they are substantial enough to last through the summer. The dogs love them. We’ve been using them for several summers now but hide them until it is time to play fetch in the water again.

Good for swimming
Size: One Size, Style: Stick
This is my dog's favorite toy for dock diving. It's lightweight but a good solid size for retrieving and it floats with no issue. I do have to keep it put away when not swimming or he'll tear it to pieces so if you have a dog that likes to destroy toys, just be mindful.

I myself have never tasted them or chewed them, but my dog Lexi goes crazy over them. I insert them into her chew toy puzzle and she is in heaven! the quality is good. the only problem with them is that my Lexi loves them so much! he is constantly bringing her chew toy over for a refill. again! Lets do it again!
