Which is the best spark plug for a Mazda Miata?
Platinum plugs are a decent choice for NC and ND Mazda Miatas but it isn’t our top recommendation. You can’t go wrong with iridium spark plugs. They’re the most widely accepted modern spark plugs out there.
What causes a spark plug to overheat in a Miata?
The size of ceramic insulation on a spark plug determines the heat range of the plug. If the heat range is too high (longer insulator) the plug itself can begin to overheat causing detonation of the fuel-air mixture. If other methods fail, you might try switching to a plug designed to run cooler.
Where can I get an ignition coil for my Miata?
Fortunately, we found a coil assembly from Mazmart in Atlanta for only $125. Now the car runs fine. The point is, don’t do a compression check without either pulling the connectors from the coils or keeping a spark plug in the wire while turning over the engine.

How do you check the ignition on a Miata?
An easy way to check is, pull #1 spark plug, and drop the dipstick down the hole. Turn the motor by hand and watch the dipstick until it peaks at top dead center. This will tell you the crank shaft is at TDC. Now check to see where the timing mark on the crank pulley lines up.
