Ignition Coil and Iridium Spark Plugs for Toyota Camry (1997-1998) 2.2L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 1997-1998 Toyota Camry

What it Does: The ignition coil and iridium spark plug service kit restores high-voltage secondary ignition delivery and stabilizes combustion flame-front propagation on 1997-1998 Toyota Camry 2.2L models.

The Stock Toyota Camry Ignition Breakdown

The factory distributorless ignition system on the 5S-FE utilizes a dual-tower waste-spark configuration. Over decades of heat soak inside the XV20 engine bay, OEM coil casings suffer from dielectric insulation breakdown, resulting in micro-arcing and secondary winding resistance drift. Compounding this, standard factory copper plugs erode at the ground strap over time. The widened gap elevates the required firing voltage, forcing heat-stressed coils beyond their saturation limits and generating P0300-P0304 misfires, erratic idle, sluggish throttle response, and incomplete hydrocarbon burn.

The Engineering Solution

This comprehensive ignition service package restores factory combustion efficiency with two dual-tower ignition coils cross-referenced to UF180 and four fine-wire iridium spark plugs. The replacement coils feature high-temperature vacuum-poured epoxy encapsulation and heavy-gauge copper windings to suppress thermal degradation and eliminate secondary internal arc-over. Paired with laser-welded iridium center electrodes, the plugs resist spark erosion and thermal shock under continuous load. The fine-wire design concentrates electrical energy to lower arc initiation voltage, preserving coil pack longevity while delivering stable spark timing across the entire RPM band.

Frequently Asked Questions

Does this fit the XV20 Camry?
Yes, this is a direct fit for the 1997-1998 Toyota Camry equipped with the 5S-FE engine.

Do these iridium spark plugs require manual gapping before installation?
No, the included iridium spark plugs arrive pre-set to factory specifications; attempting to adjust the gap manually can fracture the fine-wire iridium center electrode.

The Toyota Caliber

Known across the globe for steadfast JDM endurance, the 5S-FE platform demands precise secondary ignition voltage and robust electrode metallurgy to maintain crisp power delivery and pristine fuel economy mile after mile.
