よくある質問

詳しくはよくある質問をご覧ください。

Is the JDC COP Ignition System compatible with my Mitsubishi Evolution model?

Yes, the JDC COP Ignition System is designed as a direct replacement for factory ignition systems in Mitsubishi Evolution models 4 through 9. It seamlessly integrates with your vehicle's existing setup, providing a plug-and-play solution without the need for additional modifications.

Will I need to retune my vehicle after installing the JDC COP Ignition System?

For Denso coils- No retuning is necessary after installation. The JDC COP Ignition System is engineered to work with your vehicle's existing settings, providing immediate performance benefits without the need for additional tuning.

For Hitachi (GT-R) coils - Yes, you will need a tuner to adjust the factory dwell timing before driving with the system installed. We suggest setting the factory dwell time at 3.4ms @14v to help keep the coils cool, but you should always consult with your tuner to ensure the COP system is properly adjusted for your specific setup.

What coils should I choose for my power level?

JDC offers two types of coils for its Coil-On-Plug (COP) Ignition Systems—Denso and Hitachi GT-R coils. Both options have unique characteristics that cater to different performance needs.

Denso Coils (Standard Option)

  • Authentic Japanese-Made Denso Coils – Reliable and proven for high-performance applications.
  • Tested up to 913 WHP @ 0.020" spark plug gap – Well-suited for most moderate to high-power Evo builds.
  • Durable & Long-Lasting – More resistant to breakdown compared to cheaper, off-brand coils.
  • OEM-Level Fitment – Direct plug-and-play for Mitsubishi Evolution 4-9.
  • Recommended for stock cars up to ~900 WHP

Hitachi GT-R Coils (Optional Upgrade)

  • Higher Saturation Limit – Can handle more dwell time without overheating, making them better for extreme horsepower builds.
  • Supports Larger Spark Plug Gaps – More efficient combustion, allowing for more boost and power potential.
  • Improved Ignition Efficiency – Helps in maintaining spark energy under high-cylinder pressures.
  • Recommended for builds exceeding 800+ WHP or aggressive setups requiring more spark energy.

The JDC Recommendation

  • While the Hitachi coils provide more spark energy for higher horsepower builds, they do tend to be more temperamental and require more maintenance and tuning than Denso coils. We do not recommend using HItachi coils for cars making less than 800 WHP. Denso coils are more reliable and less temperamental making them a better-suited option for cars making under 900 WHP.
