High-performance Miata builds demand an equally capable ignition system — and the factory setup simply can’t keep up once you add boost, compression, or RPM. That’s why AMP Engine Management developed the MaxSpark PNP Ignition Kit, the most powerful and complete plug-and-play ignition solution for the 1990–2005 Mazda Miata.
Designed, tested, and Made in the USA, the MaxSpark system delivers unmatched spark energy, simplified installation, and OEM-level reliability.

Why Upgrade to the MaxSpark PNP Ignition System?
If you’ve ever battled spark blowout, inconsistent ignition under boost, or unreliable aftermarket coils, the MaxSpark PNP Kit is your solution.
Perfect for:
-
Turbo Miatas – Prevent spark blowout under high boost
-
Supercharged Miatas – Handle increased cylinder pressures with confidence
-
High-compression N/A builds – Maintain strong spark and throttle response
-
Street or track cars – Improve idle quality and drivability
Even stock Miatas benefit from stronger spark energy and smoother performance.
The IGN1A Smart Coil Advantage
At the heart of the MaxSpark system are IGN1A Smart Coils, capable of delivering up to 81,000 volts and 103 mJ of output energy at 19 amps of current.
Unlike OEM or GM truck coils, the IGN1A coils have no overdwell protection or timing drift — just consistent, powerful spark output.
If IGN1A coils can handle 60+ psi of boost in Pro Mod race cars, they’re more than ready for your boosted Miata.
True Plug-and-Play Installation
No cutting, splicing, or fabrication required — just bolt it on, plug it in, and go.
The MaxSpark PNP Ignition Kit includes everything needed for a clean, factory-style installation:
-
IGN1A Smart Coils
-
CNC aluminum coil bracket with hardware
-
Plug-and-play harnesses with color-coded TXL automotive-grade wire
-
50-amp relay and fuse for dedicated power delivery
-
High-quality spark plug wires
Year-specific secondary harnesses make setup seamless across all 1990–2005 Miata models, supporting sequential or wasted-spark ignition configurations.
Solving Voltage Drop & Reliability Issues
Factory Miata ignition circuits often suffer from voltage loss under load. The MaxSpark harness fixes this with a dedicated high-current 50-amp relay and fuse, ensuring full battery voltage to each coil and protecting both the harness and coils.
Benefits include:
-
Stronger, more consistent spark at all RPMs
-
Reduced strain on the factory electrical system
-
Improved reliability — no more relay or ignition-related failures
Built for Performance and Longevity
Every MaxSpark PNP system uses TXL high-temperature automotive-grade wire, Techflex abrasion-resistant sleeving, and labeled heat shrink for simple installation and long-term durability.
This system is built to perform under the most demanding conditions — from daily-driven turbo Miatas to dedicated track builds.
And like all AMP Engine Management products, it’s engineered and assembled in the USA.
