If you want to run LS coils on any NA or NB Miata, this is the kit for you. After years of real world performance and feedback, we’ve updated the kit: version 2 of this kit now includes new coils, and revised spark plug wires.
The bracket is made from stainless steel and mounts D585 ignition coils.
We have tested coils from many aftermarket suppliers, and each time we found that they under performed the used OEM coils we were refurbishing. Finally, we found a partner who could produce a custom coil for us that exceeds OEM performance and consistency. It’s this new custom coil that forms the basis of our V2 kit, and we continue to test every coil in house prior to shipping.
The harness is plug and play for your Miata, requiring only repinning from your OEM harness into the provided connectors for OEM-level fit and finish. The harness is wired for batch ignition, and can be upgraded to sequential. The sequential version, which would not be considered plug and play, includes wires that need to be run to your ECU. Most customers will find that the wasted spark configuration is perfectly adequate.
Our high performance 8.5mm plug wires are custom made for this kit and are a direct fit for 1990-2000 heads. The VVT head has very slightly smaller spark plug holes and can be made to fit with some trimming of the boot and fiddling - if you have a VVT head, consider this a DIY kit.
The kit includes:
1x Stainless Steel Bracket
1x Main coil harness
2x Female harness plugs
Igniter patch harness (optional extra 1990-1993 only)
4x FlowForce D585 coils
4x high performance plug wires for 1990-2000 (can be modified to fit 01+)
Sequential add-on wires (optional extra)
Note: LS coils require the use of a standalone ecu
