yeah they typically look like that. most of the time i have to chisel/dremel the coil out just to get to the plug. some times i even have to dremel the plug out, then pull a vacuum on the cylinder to extract the debris, retap and timsert the hole. boroscope and leakdown check for damage. yeah its a bitch needless to say. luckily to date i have only had 1 major issue where the plug broke and took a chunk out of the piston before they made it to the dealer. they got a new engine.

^^^ NGK only. Stick with OEM. Had another fellow S2k Challenge member on here blow his motor running Platinum Plugs from Bosch. The plug got loose and disintegrated and went into the #4 piston... that was the end of that motor.

Last sunday my engine blew up while at track. Car was running good until this session when taking out from hot pit there was little misfire. Sounded like one cylinder cutting out but it cleared up soonest I got to 3rd gear. Lap later I heard ticking and car lost power, by the time I stopped there was loud knock and smoke coming inside of the car around shift lever. No smoke outside or any oil visible anywhere.
I thought it sounded like rod knock but this morning I found different issue. One of the coils was destroyed and 2 spark plugs I can't even get out. Looks like some serious detonation going on inside the motor. Motor is stock and was running 91 pump gas. Anybody had something like this happen?
