High performance Miata builds need high performance ignitions; the stock coils typically won’t cut it if you’re running a lot of boost or otherwise increasing the cylinder pressure. And even nearly stock engines can see a smoother idle with ignition upgrades. Mazda builders have tried a lot of different ignition upgrades to get more spark, swapping on anything from GM truck coils to coils off a Toyota Camry. But these are only small upgrades, and they don’t address some of the real issues. Our IGN-1A coils will produce a very hot spark and work great on these cars, but installing them on a Miata has typically meant fabrication and custom wiring.
Our new MaxSpark kit for the Miata ignition does for the IGN-1A what the MSPNP line does for the MegaSquirt: We’ve made the IGN-1As an easy, turn-key upgrade for your stock Miata ignition! The MaxSpark PNP ignition kit for the 1990-2005 Miata will give you a substantial ignition system upgrade on your Miata with no cutting or splicing wires, no extra parts to buy, and no need to cut any sheet metal or even drill any holes. This kit includes everything you need: Coils, mounting hardware, a wiring harness that plugs into your stock wiring, and high quality spark plug wires.
And we’ve addressed one of the major weak points in the NA and NB Miata ignition system: Voltage drop. The Miata power wiring is undersized for sustained high RPM use, and it’s certainly undersized for high energy coils. Our MaxSpark harness solves these issues by adding a dedicated ignition relay controlled 50 amp ignition circuit, and does so Plug and Play. This allows for minimal voltage drop to the coils AND it takes all of the load off the Miata factory wiring and main relay. Ever had a main relay failure at the track? A lot of us have…
These coils are as hot as they get! These are race coils that can handle up to 19 amps of current, with twice the spark energy of the hottest OEM coil we’ve ever tested. They don’t have any unwelcome features like the GM truck coils’ overdwell “protection” that advances your timing if you run too much dwell (and why would you want to burn down an engine to protect an ignition coil?). No OE ignition coil solution is anywhere near as capable as the IGN1A, and we’ve made it PNP for you. There is a reason why these are the preferred coils in ProModified race cars.
But even with all their spark energy, these are very reliable coils – they’ll typically last for years of racing.
Note that 1990 through early 1995 Miatas will need to use either an aftermarket tachometer or a dedicated tach output from a standalone ECU. But if you need this kit, you probably will have a standalone ECU anyway. We’ve got you covered there, too.
Don’t settle for a minor upgrade that will let you run a few more PSI – go for a MaxSpark kit, open up those plug gaps, and have a Miata ignition powerful enough to support anything! It’s likely to help smooth your idle, too.
