We used E3 spark plugs for all our dyno testing. The company's unique DiamondFire electrode creates a mushroom cloud of spark for repeatable performance on the dyno. And if you're trying to squeak a gross-polluter through a smog check, the company's testing has shown the plugs actually reduce emissions as well. We used 100-octane Rockett Brand fuel on the dyno, but our combo will easily run on 91- or even 89-octane pump gas.
