Detailed Description

Motorad 1IC137 is a direct ignition coil engineered for stable spark delivery and reliable engine management. It uses a blade terminal layout, a single rectangular female connector, and a 12 VDC design to match the requirements of supported ignition systems. The coil is specified with primary resistance of 300-900 Ohms and secondary resistance of 3000-9000 Ohms, and it requires an external resistor.

This part is a fit for 2000-2006 Lincoln LS, 2002-2005 Ford Thunderbird, 2003-2005 Mazda 6 with Individual Coil, and 1999-2002 Jaguar S-Type. The Motorad 1IC137 is also cross-referenced with DG509 for the same application.

What It Helps Address

  • Misfire caused by weak or inconsistent spark output
  • Hard starting related to ignition coil failure
  • Rough idle from unstable coil performance
  • Loss of engine power under load
  • Heat-related ignition breakdown

Installation Notes and Tips

Verify connector style, terminal layout, and external resistor requirements before installation. Confirm the vehicle uses an individual coil ignition setup where applicable, especially on the Mazda 6. Inspect related ignition components and wiring for heat damage, corrosion, or loose connections before replacing the coil.

Quality Assurance

Motorad manufactures this ignition coil to meet or exceed OEM specifications in ISO TS16949 facilities. Engine management products from Motorad are backed by a limited lifetime warranty.
