Tempest Aviation spark plugs, which are made in the USA, include a proprietary glass center seal with a 21st century “fired in” resistor that replaces the multipart screw, spring, carbon pile stack up that are known to suffer from resistance value instability that can cause misfires, wasted fuel, and engine roughness.
The finish on the Tempest Aviation spark plugs is an environmentally preferable electrolytic nickel that provides outstanding durability, superior corrosion protection, and extreme wear resistance, according to Aircraft Spruce officials, which now stocks the spark plugs.
Purchase Tempest Massive Spark Plugs for $21.50 and the Tempest Fine Wire Spark Plugs for $49.95 from Aircraft Spruce. For more information: 877-4SPRUCE or AircraftSpruce.com
