Key Features
- Iridium-enhanced fine-wire center electrode for durable spark delivery
- Platinum ground electrode tip with tapered cut design
- Pre-gapped at 0.032 in. / 0.8 mm
- Resistor plug with 4,000 ohm resistance
- Copper core center electrode and ceramic insulator construction
- Flat seat, M12 x 1.25 thread, 1.043 in. reach, 5/8 in. hex
- Performance-grade Autolite Iridium Spark Plug line
Product Details
The Autolite Iridium XP Spark Plug line is engineered for drivers who want a direct replacement spark plug with modern electrode materials and OE-style dimensions. XP5703 combines an iridium center electrode tip with a platinum ground electrode tip to improve durability, while the tapered ground wire helps promote efficient flame travel and stable ignition performance. The result is a spark plug suited for vehicles that need reliable cold starts, smooth idle quality, and consistent throttle response. This part number, XP5703, is listed for applications including Hyundai Sonata, Hyundai Santa Fe Sport, Kia Optima, Kia Forte5, Kia Forte Koup, Kia Sportage, Smart Fortwo, Mitsubishi Lancer, Isuzu Axiom, and Isuzu Rodeo.
This part cross-references Champion Spark Plug 9060 and Monroe Shocks & Struts 5847 for the same application.
What It Helps Address
- Rough idle caused by worn spark plug electrodes
- Hard starting from weak or inconsistent ignition output
- Misfire conditions related to plug wear or gap drift
- Reduced fuel economy from inefficient combustion
- Sluggish acceleration and uneven engine response
