'91 #473 Plugs

[jss06c6]

After reading Roadster's write up on pulling and replacing plugs, I thought it would be good to do the same to #473.. Just turned 40K miles and have done a lot of tuning, but never put in a fresh set of plugs. I've ordered the NGK's, which should be here tomorrow or Tuesday. Pulled the old ones out to look at them. Not too bad, but interesting that #5 & #6 area a bit brown on the insulator, while the others are pretty clean, especially 1,2,3,4...

Having trouble again posting pictures.. I'll try as independent post..

Not too much trouble pulling #7 & #8, just used two universals and a 5/8" plug socket.. Mine all had never seize on them, so not hard to remove. Torque value was not consistent on all 8 however.. I'll correct that with the new plugs when they arrive.
