Rep Power: 0 I am not sure about the Denzo's
I just melted 2 Denzo plugs in my Lightning, The electrode and ceramic cracked off, causing damage to my cylinder head, major misfiring in both of the cylinders. Had to replace the entire cylinder head. I was told that Denzo's are great plugs and idle great however they are very week, so if you drive hard I would stay away from them. I switched to NKG, the idle is not as nice but if you compare the 2 plugs you can just see that the NGK is tougher.
