HE1HT9 Spark Plug (2 pack)

This two-pack contains Pulstar HE1HT9 spark plugs with a projected 2.6 mm Inconel center electrode and Pulstar heat range 1. Each plug combines a 12 mm thread and 19 mm reach with a flat seat and removable terminal. Pulstar's Plasmacore technology uses an internal capacitor to store and release energy.

For part-number comparisons, review the HE1HT9's projected electrode configuration, 1.25 mm thread pitch and 5/8-inch (16 mm) hex. Confirm that HE1HT9 is specified for your vehicle or engine before ordering; matching dimensions alone does not establish fitment.
