What This Part Helps Address

  • Engine misfire caused by weak or inconsistent spark output
  • Hard starting related to ignition coil failure
  • Rough idle from degraded coil performance
  • Loss of power under load due to ignition breakdown
  • Heat-related ignition issues in daily driving conditions

Installation Notes and Tips

Verify the connector style, 3-terminal blade layout, and external resistor requirement before installation. Confirm the vehicle is a 2004-2011 Mazda RX-8 and compare the original coil connector and mounting points to the 2IC148 unit before replacement. For best results, inspect related ignition components for wear during service.
