4 Flow Matched Fuel Injectors Per Order. Flow test injectors and gather data. Once injectors are back up to OE specifications they are then lubricated to extend shelf life. Reconditioning Process Back-flush to remove any internal debris left behind (multi-step process).
It was original parts that's very cheap compared to in my country. I think the parcel was a bit flimsy, should have been a hard box but all 4 injectors was in good condition. It solved my problem with the my car. I can recommend anyone to buy these as long as they fit your vehicle.
This is not the first set of injectors I have bought from this provider. For not much more than it would cost for one injector from the dealer, I replaced the entire set. Start-up and mileage improved immediately.
