Ignition Coil and Iridium Spark Plugs for Acura SLX (1998-1999) 3.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 1998-1999 Acura SLX

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces degraded factory coils and worn plugs on the 1998-1999 Acura SLX to eliminate secondary ignition misfires, stabilize idle, and restore combustion efficiency.

The Stock Acura SLX Ignition Breakdown

Under the hood of the UBS26 chassis, the 3.5L 6VE1 DOHC V6 routes its coil-on-plug pencil packs deep into the cylinder head wells. Over extended runtimes, constant thermal cycling causes the factory potting resin to micro-fracture and the silicone boots to harden. This degradation leads to high-voltage dielectric breakdown, unmetered arc grounding, and hesitation under load. Coupled with standard copper or platinum plug erosion that widens the spark gap, the aging factory system triggers stubborn P0300-P0306 diagnostic trouble codes and degraded fuel economy.

The Engineering Solution

Engineered to restore factory spark energy, this comprehensive kit features six reinforced pencil ignition coils and six fine-wire iridium spark plugs. The coil assemblies are constructed with high-grade copper windings and premium dielectric epoxy potting to withstand severe underhood thermal soak and resist internal short-circuiting. Paired with high-melting-point iridium-tipped electrodes that require less firing voltage under high cylinder pressures, this setup guarantees consistent arc initiation, crisp throttle response, and complete burn characteristics under off-camber or towing conditions.

Frequently Asked Questions

Does this fit the UBS26 SLX?
Yes, this is a direct fit for the 1998-1999 Acura SLX equipped with the 6VE1 3.5L DOHC engine.

Are the included iridium plugs pre-gapped for the 3.5L V6?
Plugs arrive factory pre-gapped, though verifying with a wire gauge prior to threading into the aluminum head is recommended practice.

The Acura Utility Caliber

The body-on-frame SLX requires consistent secondary ignition performance to pull through mud, steep grades, and heavy payloads. Renewing the ignition system ensures your 4WD drivetrain produces full torque without cylinder misfires or ignition washdown.
