JDC DIY Denso Coil-On-Plug Ignition System Kit

There is a nationwide shortage of coils at the moment, both new and refurbished. We will process all orders in the order they are received but there may be delays. Please reach out to us if you need the system by a certain time to verify stock. We will not reach out to let you know an ETA as we do not have one!

This kit includes everything you need to make your own Mitsubishi Evolution 4-9 COP (coil on plug) setup. This kit includes the exact same pieces we use to make our JDC ignition systems. If you're the kind of person that likes to save money and make your own parts, this kit is for you!

Applications:

  • Works with all Evo 4-9 USDM/JDM models (select the correct option according to the valve cover you have. Evo 9 with MIVEC is different than Evo 4-8.)
  • This ignition system is designed for use with the stock ECU and is compatible with AEM EMS V1 & V2, Haltech, MegaSquirt, and the SunAuto Hyperforce. This system will NOT work with CDI boxes or the HKS DLI and is not needed to meet your power goals up to 913whp+. 

  • This kit is designed to work with Denso coils part # 90919-02240/90919-02265. The coils are optional with this kit. You can provide your own coils if you wish.

  • Your choice of 6061 anodized satin black aluminum, carbon fiber, anodized titanium, or stainless steel "cut your own" mounting plate.
  • (2) Mitsubishi Evolution male connectors with pins and water seals

  • Better idle quality
  • Quicker and easier start especially in colder weather with E85
  • Run more boost without spark blowout issues
  • Run more gap for better fuel burn and increased mpg
  • Plugs last longer due to less fouling
  • Plug changes take minutes less
  • No problem-prone CDI Boxes
  • Noncorrosive stainless steel hardware

Note:

This kit is very simple to make for yourself if you have basic wiring or automotive knowledge and can save you a lot of money over buying a fully assembled kit. This kit uses high-quality components! If you would rather purchase a fully assembled kit or a pre-made wire harness, they are available here. You can also purchase individual pieces if you don't need an entire kit.

Packaged very well and shipped quickly came unexpected! Watched live on Instagram to build it the same time with all recommened tools. I crimped 3 of he wrong clips and had to stop the proccess, however this was no problem, contacted John, was able to order extra pieces immidiantly to ship on the way! He was completely understanding. Instructions are very easy to fallow regardless. Such a simple great MOD, will be back for more goodies!!

Thanks so much for the awesome review Aaron! I'm glad I was able to help you out on the wire building process and get your DIY COP system built! I look forward to doing more business with you soon. :)
