R-Magic now offers some upgraded engine coils for the ND (2016+) MX-5 Miata with either 1.5L or 2.0L engine. This small modification helps improve engine output (power) in the whole RPM range. On a 1.5L engine with no ECU tuning 3.3hp gains were seen from R-Magic. It prevents misfire and knocking as well. Please note that the new version of Power Coils is now RED color (see images). R-Magic Power Coils should be ordered at REV9 Autosport https://rev9autosport.com/r-magic-power-coils.html as they provide the best service and speed we've seen so far!
