Miata Coil on Plug DIY - Full HowTo!

Coil on Plugs are easy to do on your Miata. If you need a stronger spark for boost or hate replacing plug wires over and over again, then COPs are for you. In this How To we take you through what to get, how to set up the bracket, and how to wire a full plug and play harness.
If you have a 90-93 Miata, everything is similar but you'll need to connect to your igniter plug.
