muddy53 is on a distinguished road

Just replaced mine with NGK 92174 from Rock Auto for a total of 65.57 delivered, best price around. They are Copper Core Plugs that are recommended for our vehicle's.
They also offer the best performance since copper conducts better than Iridium or platinum. The only down side is that both Iridium and Platinum last longer. Iridium the longest. So the stock plugs offer the best performance, but don't last as long.
Took me about 2 1/2 hours to replace them myself and I'm good with tools.
I ended up using a 3/8" drive flex head ratchet, 2-2 1/2" extensions, 1-6" extension, 1-swivel and a 5/8" magnetic socket, Anti-Seize compound for the threads and Dielectric grease for the Coil Plug insulators.
The reason for the 2-3" extensions, made it easier near the firewall. Sometimes the 6" extension is too long.
I had to pull the ECU Connectors off and move the heater hoses to get at plug #6 and 8. PM me if you need any more info.
Good Luck
