Well ever since I rebuilt my engine and got my exhaust done, i have noticed the headers seem to be running way too hot. I used summit racing headers part no. SUM-G9003. Now I have hardly run the engine, so I understand that it should run hotter since everything is a lot more tight and hasnt broken in yet. But wouldnt that refer more to coolant temp than exhaust temp? Anyway, within the 30 minutes of total runtme i have on the engine, i have already burned out 2 spark plug wires. The wires are close, but they have at least 1/4" on each plug and I also have the heat sleeves over the ends of the wires. Something just doesnt seem right about that.
Im thinking it could be a few things:
1. Since I used a cheaper header, the actual metal thickness of the tubing is thinner thus it heats up a lot faster.
2. Since the header is only painted not ceramic coated, it runs hotter.
Now as far as I know, these are my options: please chime in with what you guys think would be the best option. I wanna do whatever is gonna get me the best result for the least amount of money. If buying a new set of ceramic coated headers is really the best way to go, then so be it but i would rather try to find a cheaper solution and make what i have work.
1. Use a exhaust wrap, ~$80 for 100 feet of 2" wide wrap
2. New set of ceramic headers ~$300
3. Get my headers ceramic coated ~$???
Now I have already tried multiple coats of 2000 degree primer and paint, and all it does is just begin to flake off within 30 seconds of the engine running.
Thank you again for all the help. If anyone has another option, please chime in
