Spark plugs come pre-gapped to 0.020". I measured my old plugs and they were reading 0.025" but otherwise looked in good condition. I see no reason why these can't be reused with a proper re-gapping. I will try it out at my next change out in 37000miles.
Couple of hints after performing this procedure:
- get yourself a knuckle-joint for the extension
- when pulling up the coil, try twisting it as well
- add some dielectric grease to the tip of the coil and where it seats on the valve cover and it won't be as hard to come out next time.
I did have a coil break on cyl 5 when the retaining clip broke and ended up giving me a misfire. So I had to purchase one online (about $60) and It took me about 15 mins to complete the swap from a completely assembled system. I do have the Dinan intakes so that may have been a factor too.
