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. ### ⭐⭐⭐⭐⭐ Fuel injectors for my cadillac cts 3.0L *by J***E on October 9, 2025* Fixed my misfire issue ### ⭐ 2016 GMC Terrain 3.6 *by R***Y on November 15, 2025* 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.
