MX-5 Ignition Coils

An ignition coil is an essential part of your MX-5, or any petrol car for that matter. Ignition coils pass electricity to your spark plugs to start your engine, but they don’t last forever. If you’re noticing your MX-5 is backfiring or stalling, it’s likely time to replace a faulty ignition coil (or multiple). Luckily for you, we stock a wide range of market-leading Mazda MX-5 ignition coils for every generation.

At BOFI Racing, we supply a selection of standard, aftermarket direct replacement ignition coils, as well as performance upgrade ignition coils for high-power applications – like the VX Pro coil options.

Frequently asked questions

How often should an ignition coil be replaced?

Ignition coils generally last between 80,000 to 100,000 miles, however, it’s always best to consult Mazda’s manufacturing guidelines, your MX-5 handbook or a mechanic. It’s recommended to inspect ignition coils every 60,000 to 100,000 miles, and then replace them as part of regular vehicle maintenance or as soon as any signs of failure are noticed. Generally, there are no hard and fast rules, just guidelines that are recommended to follow.

What are the signs that an ignition coil needs to be replaced?

Other than seeing the illuminated check engine light, you can tell an ignition coil is likely to need replacing if your car is backfiring, stalling or diminished power output. Another signifier that your ignition coil – or coils – is on its way out is noticeably lower fuel efficiency.

Beware of putting off an ignition coil replacement, as this could damage the catalytic converter or engine, resulting in a potentially eye-watering bill.

Can a faulty ignition coil cause damage to other parts of the engine?

An unchecked, faulty ignition coil can cause damage to other (often more expensive) parts of the car – like the engine, the catalytic converter and the spark plugs.
