Description

Splitfire Spark Plug. See Below for Applications.

With their original and unique V side electrode, the spark arcs across to both points creating a wider ignition point. As well, the path for combustion is open through the V to travel down towards the piston. Greater efficiency equals more power.

Nice upgrade

Used these on a 1986 2.3l Mustang that I had. They worked better than stock with better fuel mileage. Didn't feel any big power increase. But it did run better.
