Ignition Coil + Iridium Spark Plugs for Mitsubishi 3000GT (1991-1999) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1991-1999 Mitsubishi 3000GT

What it Does: The ignition coil and iridium spark plug kit replaces aged factory secondary ignition components on the 1991-1999 Mitsubishi 3000GT 3.0L to eliminate high-load misfires and maintain consistent secondary voltage.

The Stock Mitsubishi 3000GT Secondary Ignition Breakdown

The cramped transverse engine bay of the Z16A and Z15A chassis traps substantial radiant heat around the rear bank of the 6G72 3.0L V6. Over decades of heat cycles, OEM wasted-spark coil packs suffer from dielectric potting degradation and micro-cracking in the primary housing. This causes secondary voltage arcing and insufficient saturation current under boost or high cylinder pressures. Simultaneously, traditional copper plugs suffer from rapid electrode erosion, causing plug gaps to widen and overworking the factory coils until misfires occur.

The Engineering Solution

This ignition service package pairs direct-replacement wasted-spark coil packs with fine-wire iridium spark plugs to restore optimal flame propagation. The ignition coils utilize high-grade magnetic cores and reinforced epoxy encapsulation to withstand extreme thermal exposure without breakdown. Paired with laser-welded iridium electrode spark plugs, this configuration lowers the required ignition voltage, resists spark blow-out under cylinder pressure, and eliminates voltage decay across both banks of the 6G72 engine.

Frequently Asked Questions

Does this fit the Z16A 3000GT?
Yes, this is a direct fit for the 1991-1999 Mitsubishi 3000GT equipped with the 6G72 engine.

Should spark plug wires be inspected when installing this kit?
Yes, inspect secondary high-tension ignition wires for resistance exceeding factory thresholds to prevent premature coil stress and voltage leak.

The Mitsubishi JDM Performance Caliber

Preserving the performance of the twin-cam 6G72 platform requires uncompromised ignition integrity. By utilizing thermal-resistant coil construction and erosion-resistant iridium centers, this kit ensures stable high-RPM spark energy and precise throttle response across naturally aspirated and twin-turbo setups alike.
