Automotive Spark Plugs

Spark Plug Metallurgy Comparison Chart

Mileage / Service Life

Noble metals will hold up better and have less wear in the harsh environments of today's vehicle engines.

Less Mileage More Mileage

Fuel Efficiency

Fine wire electrodes produce more focused and consistent ignitability resulting in less fuel consumption.

Less Efficient More Efficient

Fouling Acceleration

Noble metals resist corrosion better, preventing fouling plugs. Spark plugs that are less likely to foul provide quicker acceleration.

Slower Acceleration Quicker Acceleration
