Ignition Coil + Iridium Spark Plugs for Acura Legend (1991-1995) 3.2L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1991-1995 Acura Legend

What it Does: The ignition coil and iridium spark plug kit replaces fatigued coil packs and worn electrodes on the 1991-1995 Acura Legend to eliminate misfires, stabilize idle, and restore crisp throttle response.

The Stock Acura Legend Secondary Ignition Breakdown

The longitudinally mounted C32A engine in second-generation Legends produces significant underhood thermal load. Over decades of operation, the factory coil packs suffer from degraded internal copper winding insulation and micro-fractures in the potting epoxy. This deterioration causes internal core resistance spikes, thermal breakdown, and high-voltage spark arcing directly through the silicone boots to the cylinder head walls rather than firing across the plug gap. Paired with aged spark plugs experiencing severe ground electrode erosion, the resulting increased resistance places excessive dwell load on the igniter circuits, leading to stumbling under load, hesitation, and unburnt fuel wash.

The Engineering Solution

This kit resolves ignition breakdown by pairing six precision-wound ignition coils with six high-durability iridium spark plugs. The replacement coil packs feature premium magnetic copper wire windings potted in thermal-shock-resistant epoxy, providing high dielectric strength and consistent primary-to-secondary step-up voltage. Heavy-duty fluorosilicone boots prevent dielectric puncture and isolate high secondary voltage within the plug tube. The matched fine-wire iridium spark plugs feature laser-welded center tips that require lower strike voltages, resist thermal ablation, and promote flame kernel expansion under high load.

Frequently Asked Questions

Does this fit the KA7 and KA8 Legend?
Yes, this is a direct fit for the 1991-1995 Acura Legend equipped with the C32A 3.2-liter V6 engine across both sedan and coupe body styles.

Should anti-seize be used when installing these iridium spark plugs?
No, modern plated plug threads do not require anti-seize; install dry and torque directly to factory service manual specifications to maintain proper heat dissipation through the cylinder head threads.

The Acura Caliber

The Honda-engineered C32A V6 requires accurate spark delivery to sustain smooth high-RPM power and factory-intended combustion efficiency. Restoring the secondary ignition circuit preserves the refined, linear powerband of your classic Japanese executive chassis.
