SPARKING PLUGS

Thank you for your note received. We are anxious to have some information on the HD.{Mr Hayward/Mr Huddy}3 Lodge sparking plugs you took out with you. Undoubtedly the tests in France are the best criterion for preignition on the road and if you will drive the car as hard as you can and see if the plugs preignite we shall have a basis to work on.
