Come guys it’s really not that bad, getting the coil plugs off is the hardest part. Here’s all the tools needed. Here’s a plug from a plug check at maybe 1000 miles on my engine some years back now when I built it. The same plugs are still in there after 6k or so, pics below and what the chambers, pistons and cylinder walls look like now when checked out a few weeks back getting ready for spring or sale whichever comes first it’s ready!
But this is running pump flex E80-83 and properly tuned. Notice how plug is clocked to face the intake valve, that is not hard to do either and helps cool the plug electrode as it’s not hidden behind the ground strap and facing the cylinder wall where flame propagation has to bounce off the cylinder wall instead of traveling towards the centers of the cylinders. Every little bit helps and every little bit can hurt, I’d rather gamble on the help side! And the plugs at check 2/8/26 is after just putting around on a 11 mile easy ride to test drive the new drive train back on Thanksgiving day, a WOT run will clean up any of that black stuff on them and cylinder head chamber.
