The heat that comes off of my pass side header seems to be much hotter then my driver side. I noticed this tonight while i was looking for arcing plug wires. i had my hand by thr valve covers. My car also has brand new plugs,wires,coil, and o2s. I also noticed that i could see a glow at every plug, and at the coil. Is this normal?
Thanks Chad

 

Normal on the slight glow. Those wires is carrying mucho voltage
