What This Ignition Coil Helps Address

• Misfire conditions caused by weak or inconsistent spark output
• Hard starting related to ignition coil failure
• Rough idle and hesitation under load
• Loss of engine performance from degraded coil output
• Heat-related ignition breakdown in demanding driving conditions

Installation Notes and Tips

Verify connector style, terminal count, and external resistor requirements before installation. This coil uses a blade terminal layout with a female connector and male terminals, so matching the original ignition system configuration is important for proper operation. Confirm the vehicle’s Bremi coil application where noted in the fitment list.

Quality Assurance

Motorad manufactures this ignition coil to meet or exceed OEM specifications in ISO TS16949 facilities. The 1IC481 is backed by a limited lifetime warranty.
