Review on 🔧 Intake and Exhaust Camshaft Actuator Solenoid Valve Kit - Replaces 12655421, 12655420 - Compatible with Chevy Cobalt, HHR, Malibu, Equinox, GMC Terrain, Pontiac G6 and more GM Vehicles - 2.0, 2.2, 2.4L by Wayne Moody

So where to start. Bought for my 07 G6 after it started turning off check engine lights and turning off traction control and killing my MPG. I read the reviews. About 40/60 junk vs good. A $26 game, so to speak. That's $26 versus the $100 you pay at Autozone when replacing Duralast or Akdelco parts. I took a chance and after replacing those VVT solenoids and a full oil change the problem was resolved. I say you take the risk. Worst case, they don't work and you return them and drive into the car zone.
