• Blade terminal type with 3 terminals and 1 female connector
• Regular grade construction with black and white housing
• Secondary resistance: 16,500-24,500 ohms
• Requires external resistor
• Designed to meet or exceed OEM specifications
• Manufactured in ISO TS16949 facilities

Fitment and Application Details

Compatible with 2001-2006 Kia Optima, cylinder(s) 2, 4; 1999-2005 Hyundai Sonata, cylinder(s) 2, 4; 2001-2004 Hyundai Santa Fe, cylinder(s) 2, 4; and 1999 Hyundai Sonata.

What This Ignition Coil Helps Address

• Misfire conditions caused by a weak or inconsistent coil output
• Hard starting related to ignition voltage loss
• Rough idle from degraded spark delivery
• Engine hesitation during acceleration
• Heat-related coil breakdown in demanding operating environments

Installation Notes and Tips

Verify the connector style, terminal count, and cylinder location before installation. This coil uses a female connector, male blade terminals, and an external resistor requirement, so confirm the vehicle’s ignition setup matches the OE configuration before replacement. Inspect related ignition components and wiring for heat damage or corrosion during service.

Quality Assurance

Motorad designs its ignition coils to meet or exceed OEM specifications and manufactures them in ISO TS16949 facilities. The 1IC143 is backed by a limited lifetime warranty.
