Question about running temp

[ORION]

Dumb question.....
I'm tuning my 90SC up and am going to replace the spark plugs. What is the typical running temp?
What would be the best plugs to use?

If the vehicle is pretty much stock, then the OEM plugs or equivalents are the best way to go. You can tighten the gap up a bit though, from the stock .054" to around .045" to .048", to lessen the chance of misfire under boost.

Platinum tip plugs will generally last longer, but if you don't mind changing the plugs more frequently, then the less expensive copper core ones will be fine.
