Was just about to buy more spark plugs for the LS cause still chasing a very minor occasional misfire at idle and was just hoping the plugs got fouled cause of the previous oil leak (before my valve cover gaskets were changed)
But any thoughts on these Ruthenium HX ones?

Or should I go with the normal NGK Laser Iridium plugs?
