CAT Fit Caterpillar Perkins C6.6 320-0680 6PCS Fuel Injectors 2645A747

Bought these for a neighbor. He said all of them worked really well and installed easily.

The injectors work had to replace the o rings they didn't seal 4 out of the 6 sprayed gas all over.

The engine picks up speed cleanly now without the uneven diesel knock it had before. Exhaust smoke has also decreased during cold operation.

The engine settled into a cleaner idle after replacing the faulty injector. Throttle response improved as well, and the part has performed reliably so far.

Probably the best you can expect for the price
