Buying Guide: NGK Spark Plugs

Standard Spark Plugs
Standard plugs are constructed for longer life and optimum performance. Match the number on your old plug before you order.

V-Power Spark Plugs
One V-Power plug is designed to operate over a much wider heat range than ordinary plugs, and it resists carbon buildup and pre-ignition. Another V-Power plug has a v-cut in the center electrode that directs the spark to the edge of the electrode, which increases ignitability and reduces quenching, and it is sold in a pack of 4.

Gaps, Hex Sizes and Pack Sizes
Several plugs in this lineup have a 0.028 in. gap, and one has a 0.03 gap. One plug is 14 mm with a 5/8 in. hex, and another is sold in a pack of 10. Compare the gap and hex size with your old plug before you order.
