Autolite Iridium XP Spark Plug XP5426
Autolite XP5426 is an iridium spark plug built for stable ignition performance in a range of Chrysler, Dodge, Jeep, and Volkswagen applications. It uses a fine-wire iridium center electrode, a platinum ground electrode tip, and a tapered ground design to support efficient combustion, consistent starts, and responsive throttle behavior.
Key Features
- Iridium-enhanced fine-wire center electrode for durable spark delivery
- Platinum ground electrode tip with tapered cut design
- Pre-gapped to 0.050 in. / 1.3 mm for listed applications
- Resistor-type plug with 4,000 ohm resistance
- Ceramic insulator, copper core center electrode, and nickel ground electrode core
- M14 x 1.25 thread, 25 mm reach, tapered seat, 5/8 in. hex
- Performance-grade spark plug for secondary ignition service
Product Details
The Autolite Iridium Spark Plug line is engineered for drivers who want precise ignition control and long-lasting electrode materials in everyday and performance-oriented use. XP5426 combines an iridium center tip with a platinum-tipped ground electrode and a fine-wire center design to promote reliable spark initiation, improved ignitability, and efficient engine operation. This part number is used in applications such as the Jeep Wrangler, Chrysler Town & Country, and Dodge Grand Caravan, along with other listed vehicles in the fitment data. This part cross-references Champion Spark Plug 7440 for the same application.
What It Helps Address
- Hard starting caused by worn or inefficient spark plugs
- Rough idle from inconsistent ignition performance
- Reduced throttle response from degraded spark delivery
- Fuel economy loss related to weak combustion efficiency
- Misfire concerns tied to worn center or ground electrodes
Installation Notes and Tips
Verify thread size, reach, seat type, and pre-gap before installation. XP5426 uses a tapered seat, M14 x 1.25 thread, 25 mm reach, and a 0.050 in. gap for the listed applications. Confirm the vehicle’s ignition service requirements and inspect coil boots, plug wells, and threads during replacement. For fitment examples, this plug fits 2007-2011 Jeep Wrangler, N/A; fits 2001-2010 Chrysler Town & Country, N/A; and fits 2001-2010 Dodge Grand Caravan, N/A.
