Thats why I had dealer do my plugs and wires. I did the airshocks and air pump myself but wanted to save my back so dealer for plugs.

I get it if you have a bad back, it can contort you in weird ways.

Overall not too bad, there was adequate room but tight. Was a number of different small extension combinations for the full process.

The stool positioned in this manner really makes a big difference with a firm footing.

@Rocket Man has a trick for that plug.

I guess I better get ready to do my plugs. They have 132k on them.

#8 plug trick: use a regular depth 3/4” socket on the end of a magnetic 5/8” plug socket. Put the plug socket on the plug, and use the ratchet/ 3/4” socket combo to wrench it. There’s a reason for the socket end on ratchet side the plug socket. It makes the perfect length to get #8 out. No other extensions, etc. Try it!

Use AC plugs or NGK. Do not use Bosch, the LS engines don't like them.
