Ignition Coil and Iridium Spark Plugs for Honda Passport (1998-1999) 3.2L

Direct-Fit Ignition Coil and Iridium Plug Kit for 1998-1999 Honda Passport

What it Does: The complete ignition kit replaces degraded factory coil packs and worn plugs on the 1998-1999 Honda Passport to eliminate misfires, stabilize idle, and restore combustion efficiency.

The Stock Honda Passport Thermal Breakdown

Mounted deep within the DOHC cylinder heads of the 6VD1 engine, factory pencil coils endure intense thermal cycling and oil-vapor exposure. Over time, the internal epoxy insulation suffers dielectric breakdown, leading to micro-cracking and secondary voltage loss under load. Coupled with standard factory plugs prone to electrode erosion, the weakened ignition system triggers intermittent P0300-P0306 DTC codes, rough idling, hesitation during acceleration, and unburnt fuel entering the exhaust stream.

The Engineering Solution

This drop-in ignition overhaul utilizes high-dielectric epoxy housing and precision-wound copper secondary windings engineered to resist thermal degradation and internal shorting. Each coil features heavy-duty silicone boots to seal out moisture and prevent spark flashover. Paired with fine-wire iridium spark plugs, this kit requires lower firing voltage while delivering a consistent, high-energy spark across all load transitions. The 0.6mm iridium center electrode resists spark erosion, outlasting copper and platinum designs in harsh combustion environments.

Frequently Asked Questions

Does this fit the UER25 Passport?
Yes, this is a direct fit for the 1998-1999 Honda Passport equipped with the 6VD1 3.2L V6 engine.

Are the iridium spark plugs pre-gapped?
Yes, the spark plugs are factory pre-gapped for the 3.2L engine, though verifying gap specs prior to threading is standard practice.

The Honda Towing & Utility Standard

For an SUV relied on for trail duty and utility towing, complete cylinder combustion is mandatory. Delivering consistent spark under sustained heavy-throttle load protects expensive catalytic converters and preserves low-end torque output across uneven terrain.
