Code No. 43005-AT002



Increases energy output up to 1.6 times compared to OEM. A strong spark prevents the misfire even at the high rpm range.






  • By mounting the ignition coils away from the heat source, the life of the plugs are improved.
  • To ensure efficient and consistent ignition, the simultaneous ignition has been upgraded to an independent ignition system.
  • Black anodized bracket to ensure aesthetics and durability. 
  • Made in Japan to ensure high durability and performance.
  • The degraded OEM harness can now be refreshed with the included dedicated harness.
  • Specially designed brackets and harnesses allow for easy bolt-on installation.
  • Each coil contains a built-in igniter, eliminating the risk of failure of the degraded OEM igniter, which can now be removed.





The coil boots and coil springs are made from materials that are heat-resistant and can withstand high voltage. Able to support reliable ignition in harsh environments, such as the difficulty of spark at high engine load.
