SPARK PLUGS: Just A Data Point

[RUFFSTUFF]

So I'm replacing the plugs in my car right now. Pulled the first plug, and just wanted to share...

Denso 5346 IKH24, gapped at install to 0.020"
36,000 miles (or so) running 93 pump, many tanks of E30, and downed 3 32oz bottles of Boostane Pro. Mods in profile, Map3 or Map5 daily driven.

Now the gap is 0.058" WHOOP! The electrode is mostly gone. So I'm thinking no more than 20k intervals on replacement? Probably won't run Boostane much anymore.
Anyhow, installing Denso 5347 IKH27, gapped to 0.020".

Good times.

I was just wondering whether it was time to change plugs (I'm at 23K).

Guess that's a yes!

Thanks for the heads-up.

The gap on this one was the best... 0.045". Every other one was about 0.058". Don't have an idea why one plug was different.

If I had know the plugs were going to be so worn I would have run a few logs to see what was going on...
