[QUOTE=BMO;929592]Me too, joeyav!

Last evening I had time to pull just three of the plugs. I tested the wires and they look in good condition and tested @ ~2200 ohms each. The plugs (NGK TR55) look good but were gapped to 0.062. I regapped them to 0.40 and reinstalled. This is my daily, so had to get it back together.

I have new plugs and wires on order and will swap them all out when they come in.

BMO >> NGK TR55 is not a recommended plug for your SRT6. Should be NGK plug # IFR6D10 Laser Iridium or a compatible plug to that spec. Go to their web site and search plugs, you will find 7 listings. I do not see a TR55 listed. On their PFR6T-10G Laser Platinum plugs they show a stock number of 5542. Maybe that is what you have?? It does have the gape at .040"
