Review on GM Genuine Parts 89060413 Intake Manifold Gasket Kit: Ensuring Reliable Performance with Side Intake Gaskets by Angel Scully

Revainrating 5 out of 5

OEM parts equivalent

Exact replacement for 5.3 with cathedral connectors (07 Silverado Classic) Snaps in and is very easy to change if knock sensors are installed (if you make these sensors be sure to change them harness, don't come back because you missed part 1). Also, don't forget to tighten those inlet screws, you don't want to over-tighten that gasket or plastic manifold.

Pros
  • Excellent overall performance
Cons
  • Hard to tell
