Detailed Description

MotoRad 1IC425 is a direct ignition coil designed to restore proper spark output in vehicles that use an OE-style coil configuration. It is listed as an OE replacement and cross-references applications such as 12594176, 12670154, 8942226130, 8942226131, 8942489840, and D596A. This part is a fitment match for 2006 Buick Lucerne, 2006 Cadillac DTS, 2006 Cadillac STS, and 2006 Cadillac XLR, including XLR applications with Individual Coil or Separate Coil. For drivers searching for a 2006 Buick Lucerne ignition coil or a 2006 Cadillac DTS ignition coil, the 1IC425 provides a direct replacement path.

What It Helps Address

  • Misfires caused by weak or inconsistent spark output
  • Hard starting related to ignition coil failure
  • Rough idle from degraded coil performance
  • Loss of engine power under load
  • Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the connector style, terminal count, and external resistor requirement before installation. Confirm the vehicle uses a direct ignition coil layout and match the OE replacement reference to the original part number. On 2006 Cadillac XLR applications, check whether the vehicle uses Individual Coil or Separate Coil configuration before ordering.

Quality Assurance

MotoRad designs this ignition coil to meet or exceed OEM specifications and manufactures it in ISO TS16949 facilities. The 1IC425 is backed by MotoRad’s limited lifetime warranty.
