Detailed Features and Specifications

The Champion Iridium 9440 spark plug features a fine iridium center electrode tip that provides a stable spark and improved wear resistance compared to conventional plugs. The ground electrode incorporates a platinum core with a J gap design, which helps maintain consistent spark gap and ignition reliability over time. The non-removable nut electrical terminal ensures secure connection within the ignition system. With a pre-gap size of 0.053 inches (1.35 mm), this plug is optimized for efficient combustion in compatible engines.

The spark plug’s tapered seat and 14 mm thread diameter allow for proper sealing and fitment in designated Chrysler, Dodge, Jeep, and Volkswagen models such as the Caravan, Grand Caravan, Pacifica, Routan, Stratus, Town & Country, Voyager, and Wrangler. The resistor built into the plug reduces radio frequency interference, supporting stable vehicle electronics. Installation is facilitated by the 16 mm hex size, providing compatibility with standard spark plug sockets.
