Review on πŸ”§ GM Genuine Parts 12679525 Fuel Injection Throttle Body: Efficient Performance with Throttle Actuator by Josh Cooper

Revainrating 3 out of 5

2003 6.0 Yukon Denali

My truck runs like new again! I got "reduced engine power" and thought it was the numerous ground wires on GM trucks that always corrode and break. After installing this new throttle body, my transmission shifts perfectly and my CEL shifts as well. I installed it myself in about 2 hours as the coolant hose clamps are PITAs that need to be removed/installed first. Looks like a genuine GM part as it has the same markings as the old one. EDIT 6-1-2020 I bought this throttle body less than 6 months ago and it has already failed. My truck started to "reduce engine power" again, to the point where I couldn't even drive it 1 mile and it broke. I had to buy another one, let's see how long it lasts.

Pros
  • Excellent Design
Cons
  • Faulty
