MaxSpark IGN1A Ignition Kit - GM LS Engines

Take your GM LS engine to the next level with the MaxSpark Plug & Play IGN1A Ignition Kit—AMP|EFI’s ultimate high-performance ignition solution. This complete drop-in system features high-output IGN1A smart coils, billet mounting brackets, Magnecor plug wires, and a premium plug-and-play wiring harness that surpasses OEM quality. Whether you're running a factory ECU or aftermarket system like MS3Pro, this ignition kit delivers cleaner idle, smoother cruise, and the spark intensity to support high boost, high compression, nitrous, or methanol builds. Key Benefits Unmatched Spark Energy: IGN1A coils deliver over 100 mJ per spark, nearly twice that of stock LS coils. Ideal for high-horsepower and high-boost builds. No More Spark Blowout: Supports high RPM, high cylinder pressure, and aggressive tuning with zero misfire. Smoother Operation: Improved idle, throttle response, fuel economy, and reduced emissions from more complete combustion. Bolt-On Simplicity: Fully PNP harness and coil brackets mount to factory LS valve covers. Fuel Efficiency & Power: Real-world gains from cleaner combustion—many customers report being able to lean out their fuel tables with no loss in AFR. System Compatibility Works with: Factory LS ECUs, MS3Pro, and other aftermarket ECUs capable of coil-per-plug control. Not compatible with: LS9/LSA engines (due to integrated coil/fuel harness and bracket fitment).
