Ignition Coil and Iridium Spark Plugs for Isuzu Trooper (1998-1999) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1998-1999 Isuzu Trooper

What it Does: The ignition coil and iridium spark plug kit replaces worn factory secondary ignition components on the 1998-1999 Isuzu Trooper to eliminate cylinder misfires, stabilize idle rpm, and restore optimal combustion efficiency.

The Stock Isuzu Trooper Ignition Breakdown

Under the hood of the UBS26 chassis, the 6VE1 3.5L DOHC V6 operates with tight spark plug tube clearances that trap extreme thermal load. Over extended run cycles, the factory pencil coils suffer from epoxy potting degradation, dielectric insulation breakdown, and micro-cracking across the lower silicone boots. This deterioration allows high-voltage arc flashover to ground rather than jumping the plug gap, triggering severe hesitation under load, P0300 through P0306 DTC codes, unburned hydrocarbon catalytic wash, and poor fuel economy from widened factory copper plug gaps.

The Engineering Solution

This comprehensive tune-up kit replaces all failure-prone secondary ignition components with six high-dielectric pencil ignition coils and six fine-wire iridium spark plugs. The ignition coils feature heat-resistant thermoplastic housings with reinforced internal copper winding spools, ensuring high-energy primary-to-secondary voltage transfer without thermal breakdown. Paired with laser-welded iridium-tipped center electrodes and platinum-enhanced ground pads, this kit provides a concentrated spark kernel, lowered required firing voltage, exceptional resistance to gap erosion, and reliable cold-start ignition across high-stress driving conditions.

Frequently Asked Questions

Does this fit the UBS26 Trooper?
Yes, this is a direct fit for the 1998-1999 Isuzu Trooper equipped with the 6VE1 3.5L V6 engine.

Do the iridium spark plugs require manual gapping prior to installation?
No, these plugs come pre-gapped for the factory 3.5L application; adjusting the fine-wire iridium tip risks damaging the laser-welded center electrode.

The Isuzu Heavy-Duty Standard

Built to handle harsh backcountry trails and heavy off-road utility, these coils and iridium plugs provide the spark energy and heat tolerance needed to keep your Trooper operating reliably under demanding towing and off-camber loads.
