I put 106s in my car today as part of normal maintenence. Every post I have read on this site says they are too hot. Why? They are listed as stock replacement plugs, so I thought they would be fine. Am I wrong? Could they hurt my engine?

 

I've never had a problem with em....

 

They are 1/2 heatrange hotter than stock IIRC.

 

Can they hurt my engine? It is running great. I gapped them at.050

 

They'll be OK. I've had in my car for a long time with no problems.

 

Good to know. Thanks for letting me know.

 

they'll be fine as long as youre not spraying

 

Nope, no spray for me. I have enough problems keeping rearends in it.
