What It Helps Address

  • Misfires caused by worn or damaged ignition wires
  • Hard starting related to weak spark delivery
  • Rough idle from inconsistent ignition output
  • Loss of engine performance from deteriorated wire insulation
  • Service needs during ignition system maintenance on Hyundai Santa Fe, Kia Amanti, and Hyundai XG350 models

Installation Notes

Verify engine configuration and production date before ordering, especially for the 2002 Hyundai XG350 note requiring vehicles made on or after 9/1/2002. This Karlyn-STI 784 wire set is listed for applications with 3 leads, while the remaining cylinders use direct ignition PN[5040] for a complete tune-up. Match each lead to the original routing and coil or plug locations during installation.
