Let's face it. In the grand scheme of building an engine, spark plugs are often an afterthought. Since they don't actually increase airflow into an engine, how much can spark plug design actually ...

Overall gas mileage over a 4000-mile test period improved from the previous standard-design plugs' 8.99 to 9.42 mpg with the V-gap plugs, a 4.78-percent gain. We hope to be able to report engine ...

To find out, we consulted leading spark plug manufacturersincluding Bosch, Champion, Denso, and SplitFireto get the lowdown on modern high-performance spark plug design and application.

The design of the spark plug really hasn’t changed very much since the gasoline engine was invented–they’re a device that creates an electric spark across a very precise small gap to ignite ...
