The fuel injector sprays a precisely metered, atomised amount of fuel into the cylinder or intake port at the exact right moment for efficient combustion.
Choose used injectors by the complete manufacturer’s reference, injection system and engine application. A wiring loom or sealing washer is not an injector assembly. Ask whether test results relate to the actual unit, and check any coding and fitting-material requirements with the workshop. A similar number or matching connector alone does not establish interchangeability.
If you notice any of the following, the part likely needs replacement:
Rough idle or misfire on a specific cylinder
Poor fuel economy
Check Engine light with an injector-related fault code
Fuel smell or a leak visible at the injector
Installation information
Requires relieving fuel system pressure before removal — always fit a new sealing O-ring/washer when installing.
Frequently asked questions
A faulty injector delivers too much, too little, or unevenly atomised fuel to its cylinder, disrupting that cylinder’s combustion and causing a noticeable misfire or rough running.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
