Review on Enhanced Power LS Coil Upgrade Harness by MSD - Model MSD 88867 by Kenneth Barnes

Revainrating 5 out of 5

2003 Silverado 4.8L & 2013 Caprice PPV 6.0L

Used MSD wiring harness to bridge between OEM wiring harnesses. Worked great. Don't take off your spools like me and then drop one. With this you just connect the connector and then connect it to the battery. Noticed smoother shifts and slightly more power. With the Caprice, I also noticed smoother shifts, quicker starts, and more power. Clamp coils and wires, but I also have MSD connectors.

Pros
  • Automotive
Cons
  • Socket required
