Ignition Coil + Spark Plugs for Infiniti I30 (1996-1999) 3.0L

OEM-Grade Direct Replacement Ignition Coil & NGK Spark Plug Kit for 1996-1999 Infiniti I30 (A32)

What it Does: The Ignition Coil and Spark Plug Kit replaces deteriorating factory ignition components on the 1996-1999 Infiniti I30 to resolve cylinder misfires, restore clean combustion, and stabilize erratic idle speed.

The Stock Infiniti I30 Ignition Breakdown

Under-hood thermal cycling on the transverse VQ30DE engine severely compromises the factory ignition architecture over time. The rear bank ignition coils (cylinders 1, 3, and 5) sit trapped under high heat soak beneath the intake manifold plenum. This prolonged thermal exposure degrades the internal epoxy potting and causes insulation breakdown in the secondary winding copper wire. Combined with aging, eroded spark plug gaps that demand excessive secondary voltage, the fatigued OEM coils suffer internal arcing, erratic dwell times, and breakdown under load. This commonly triggers P0300 multi-cylinder misfire codes, rough acceleration, and unburnt fuel fouling the catalytic converters.

The Engineering Solution

This comprehensive refresh kit pairs high-dielectric epoxy-encapsulated ignition coils with precision-gapped NGK Platinum spark plugs. Built to exceed OEM thermal resistance parameters, these coil packs utilize heavy-gauge magnetic copper windings and reinforced silicone boots to eliminate high-voltage spark leakage and carbon tracking. Matching fresh coils with platinum-tipped fine-wire electrodes lowers the required breakdown voltage from the ignition module, ensuring consistent arc duration and complete flame-front propagation across the combustion chamber.

Frequently Asked Questions & Fitment Warnings

Does this fit the A32 I30?

Yes, this is a direct fit for the 1996-1999 Infiniti I30 equipped with the VQ30DE 3.0L V6 engine; it is not compatible with later 2000+ A33 chassis variants using the VQ30DE-K.

Are secondary spark plug wires required with this kit?

No, the A32 platform utilizes a coil-on-plug (COP) direct ignition architecture, meaning each coil mounts directly over the spark plug tube without secondary plug wires.

The Infiniti Caliber

The legendary VQ30DE is celebrated for its balanced, silky-smooth power delivery. Installing matched coils and plugs ensures balanced cylinder pressures and crisp, reliable throttle response worthy of Nissan's award-winning V6 architecture.
