Review on πŸ”§ Enhance Engine Performance with GM Genuine Parts 12669184 Engine Valve Lifter Guide by Jason Guzman

Revainrating 1 out of 5

Do not rely on the installation instructions!

The installation manual is totally useless as it and its parts descriptions show or ask if it's for Delete On Demand app or not! Apparently the standard install guide lists a Delete On Demand engine for a 2007 Chevy Silverado 1500 with a 5.3 engine as this was sent to me even though my engine is NOT DOD equipped!

Pros
  • Genuine GM parts are engineered, engineered and tested to strict standards and backed by General Motors.
Cons
  • 0
