Ceramic plug wires: fixed it, then regretted it

I ordered a new set of wires and it cleared up the misfire. The idle stumble went away too. Nice bit is these have ceramic boots that won’t melt and have integrated fiberglass insulation to protect them from headers.

I also put the 2nd MPI hub on the passenger rear. Not because it was making noise, but having the different design on one side changed the rear enough to feel in the alignment. I figured I might as well even it out since I had the part. Underbody inspection revealed one exhaust manifold lost two nuts at the flange somehow. I also applied RTV to stop a slow seep at the transmission and diff junction. Saturday I’m headed out to an autocross with the car. It’ll be interesting to see how I place in the new car since this is the group I won the championship with in the M4.

edit- Ceramic boots ended up being a bad idea. I kept having them pop off when the car hit a kerb on the track. G forces plus a little jostling was enough to pull them off. Plus they were a little long. I think the built-in insulation is a great idea, but I think I’ll stick to silicone boots in the future.
