    Whaat are the correct spark plugs for a 27 series 80 engine?  The engine currently has Champion w-20’s.  I understand that Champion 518’s will also work.  Any others?

    Hi Rod, unless your car is an oil burner, the cooler W-18 / 518 should work well.  Autolite 3076 (probably equivalent to W-16 / 516) is a tad cooler yet, and that’s what I run in my S80.
