the R stands for Resistor. It is a resistor plug.
what is the difference between dual and single pin spark plugs
The Packaging. Autolite MAKES Motorcraft
RDJ7Y Champion
it uses a RDJ7Y
It is debatable but has been known to put out a better spark do to the positioning of the angle spark plugs, but how much more affective this is I dont know.
One has 4 spark plugs
it uses a RDJ7Y
Champion RDJ7Y is the correct number.
No, one has a j at the end and the other has a y.
A spark plug actually sparks, and is generally only used in a gasoline engine. A glow plug just gets warm (glows), and is used in some diesel engines.The difference between spark plugs and glow plugs is that a spark plug delivers current from an ignition system to the combustion chamber while a glow plug is a heating device that aids starting diesel engines.A spark plug actually sparks, and is generally only used in a gasoline engine.

Platinum spark plugs are better becacuse they last longer than plugs with traditionalcopper electrodes when they are worn out from electrode deterioration (which is the mostcommonreason for failure).They can last twice as long.Theymay notlast any longer if the plugs are fouledby depositsdue to other problems.
Changing your spark plugs could theoretically make your car faster but not enough to make a noticeable difference. Changing your spark plugs when they are worn will increase your fuel mileage slightly.
