SsangYong A6640170221 is the common rail injector: the black body with the threaded inlet and leak off port, the two pin plug and the nozzle with its copper washer. It is used on SsangYong Actyon, Kyron and Rexton. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
The same part is also sold as Delphi EJBR04701D.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Rough running and misfire
A worn or sticking injector sprays unevenly: the engine knocks, misfires or idles rough. A cylinder cut-out test finds the bad one.
Smoke and fuel use
Black smoke and rising fuel use point to dribbling nozzles. Replace injectors before they wash the cylinder walls.
Hard starting
Leaking injectors bleed fuel pressure back and make the engine crank longer, especially when hot.
Fitting tips
Fit new copper washers and seals, clean the seat in the head, and torque the clamp to the engine maker's figure.

Yes, it is a direct replacement for the SsangYong A6640170221 with the same fitting.
Often 5,000 to 10,000 hours, but much less on poor or wet fuel. Injectors are usually changed when they fail a test, not by hours.
Black or white smoke, a misfire or knock on one cylinder, hard starting, higher fuel use, or a high return leak or balance rate on test.
Most common rail injectors carry a trim code (QR or IMA) printed on the body. Enter it with a diagnostic tool after fitting, or the engine runs rough and smokes.
Always. Fit a new copper washer and O-rings under every injector you remove. A reused washer leaks combustion gas and carbon packs the bore.
No. It is an aftermarket fuel injector made to replace the SsangYong A6640170221. It is not made by the original manufacturer; the number only shows what it replaces.
