Spark plugs

District spark plugs are manufactured using the very best materials. With pure iridium central electrode and trivalent platinum plating on the cathode, District spark plugs are extremely wear-resistant and anti-fouling. Carbon and oil deposits won’t stop the sparks because the fine tip quickly burns off the deposits. The double iridium models sport fine wire iridium welded to the cathode, for extra long life and performance. 95% alumina oxide insulator ensures very high dielectric breakdown voltage, allowing consistent spark under high engine combustion pressure. This will allow the plugs to deliver clean sparks for a long time.

Be mindful of cheaper knockoffs that look like they are iridium, but are actually steel core that runs all through the spark plug and tapered to look like the real deal. These spark plugs greatly complement our ignition coils for ultimate performance.
