Photos of 100k mile plugs out of my C5
100k mile plugs from my 2003 C5.
Plugs
Plugs and wires.
Finally did it after record setting procrastination. My 2003 with exactly 100,000 Miles was running fine and averaging 22mpg with a 70/30 mix of highway and town driving and great acceleration. But I finally did the deed - it was not fun but shops wanted $250-$350 labor to do the work here in the Denver area.
Anyway, here’s some pics of the old parts just for fun. Yes it does seem to be running better but I’ll wait to check my next tank for mileage plus pedal to the metal a few times to swear to that. Pretty impressive durability.

With my past Vette's, C3/C4's I found you really needed to at least change wires every 30-40K to run well for sure. The car ran fine and fine MPG still with these 15 year old parts! I am curious to see MPG of my first full tank on the new parts though, it sure seems to be running stronger but that could be in my head. Not a fun job when you let them go that long, getting them out was tough. Lots of penetrating oil and patience and bloody knuckles.

I did it right, believe me. Though I doubt I’ll still be around when’s these plugs are due for a change. You’ll all have flying vettes by then.

Yep. They say they have a special coating plus the lubricant can cause you to over torque by 20%. Makes sense.

If you are changing plugs frequently, in a nitrous application for instance, I would not put anti seize on the threads every time as some stays on the cylinder head. Further too much antiseize getting built up can lead to problems.
