Great buy so far
Perfect fit. Great quality. The quantity is worth the money. It wasn’t easy to install but I’m sure it depends on the car. They work great.

2016 GMC Terrain 3.6
Began having problems after installing these injectors on 2016 gmc terrain 3.6 liter.. Car started stalling at stops and in reverse. Scanner had random codes for O2 sensors bank 1&2. Another code that vehicle was running rich. Replaced O2 sensors, Replaced ignition coils with OEM and also Replaced HPFP OEM and still had same problem. I ordered OEM fuel injectors $68 each and just today I installed them and drove the car for 100 miles with no issues and 0 codes. After all that money spent the problem was the injectors. Lesson learned

Can't beat from our experience the quality or price.
2011 Chevy Equinox's 2.4L AWD - LT Engine - LAF Worked great after narrowing it down to 1of the 4 injectors which was cylinder #2 injector using ODB2 scanner and the following codes below and trial of elimination. To make sure it wasn't a bad spark plug or bad ignition coil I swapped #2 ignition coil first to #3 and #3 to #2. Started, running rough idle and It was the same codes and no change in ODB2 readings. Then to check the spark plugs I did the same for the spark plug while leaving the coils that I had switched alone and not switching back to their original spots. So spark plug #2 went into #3 and #3 to #2. The codes didn't change leaving only the injector #2 or wiring to that injector #2 and so with this option on Amazon for 4 injectors gave it a shot arrived the next morning and replaced all 4 injectors at the same time with having the intake manifold off and the injector fuel rail off and once installed, put back together and started for the first time.... all codes were cleared and into historic faults.... Check engine light was off and in over 300 miles with numerous cycles of the car it has not come back on and the engine is running smooth, no smoke, fuel usage is normal, etc. P0302 - Powertrain Cylinder 2 Misfire Detected P0202 - Powertrain Injector CIrcuit - Cylinder 2 P0420 - Powertrain Catalyst System Efficiency Below Threshold (Bank 1)
