Message	Check the heat range of the plugs and gaps. Check O2 sensor readings for rich biased readings causing the car to lean out increasing cylinder temps. Car running hotter than normal will also increase cylinder temps. Check cooling system. EGR deleted will make them higher also but mine passed without it a few years back when we still had Emission testing. Coming soon!! Zspeedperformance.com
