Stock ECU Coil on plug conversion (COPs) Kit (Plug and Play)

Works with your OEM ECU
In stock
Product Details

Yes you are reading that right, GFBDevelopments have now produced a COPs kit for owners of cars with stock ECU's

So why?

The OEM coil packs in your beautiful MX5/Miata are possibly 20+ years old now, possibly look worn out and generally not performing very well. Owners of BIPES or PiggyBack ECU's can also take advantage of this produce due to it's full support on those setups.

Project81's stock ECU COPs version, gives you all the benefits of better performing coils and none of the negatives.

Project81 requires no mounting bracket which gives it that OEM look.

With the kit you will get:

Plug and Play COPs harness


Voodoo Ignition box

Fitting instructions

Spark Plugs (Optional)

ALL of our kits are plug and play, meaning you wont need to mess about with soldering or sourcing connectors.

Like our other version of Project81, this uses quality components (not copies).

NOTE. When selecting the kit you have the option for Boost and Unboosted coils, this is simply a futureproofing option. Should you pick the Boosted version and swap to aftermarket ECU and forced induction, the coils wont need to be changed.

Our kits come with our A* support and guidance 24/7 and are back by our manufacturers warranty.

Upgrade your Spark with GFBDevelopments.

This kit requires specific spark plugs, be aware your current NGK plugs will NOT work.


If your car is an NA (MK1) pre-1995 you may need an additional Tach adapter. This is an easy aspect to check:

If the car is a 1.8: Remove coil pack connector from one of the coils (back of head), count the pins on coil pack (NOT CONNECTOR). IF 4 Pins - Tach adapter required.

If car is a 1.6 MK1 NA - Tach Adapter required

To Keep the costs of the kit low, the Coils are used this means they may have some surface marks etc. All coils are tested prior to shipping and thus the marks are superficial.

Tach Adapters can be purchased elsewhere as it is not something we stock. One of our team can advise (Cars with aftermarket ECU's do not need to take this into account).
