Ignition Coil and Iridium Spark Plugs for Ford Fiesta (1998-2001) 1.3L

High-Reliability Ignition Coil and Iridium Spark Plug Kit for 1998-2001 Ford Fiesta

What it Does: Replaces degraded factory ignition components with high-conductance copper-wound coils and fine-wire iridium spark plugs to eliminate misfires, stabilize idle, and restore combustion efficiency.

The Stock Fiesta Ignition Breakdown

Over continuous thermal cycles in the compact engine bay of the Fiesta, factory ignition coils experience internal dielectric breakdown and microscopic housing fractures. Coupled with rapid electrode erosion on standard copper core plugs, this degradation causes severe secondary voltage leakage, intermittent spark blowout under load, sluggish throttle response, and unburnt fuel entering the exhaust stream.

The Engineering Solution

This direct-replacement ignition kit features coil-on-plug assemblies engineered with high-purity internal copper windings and heavy-duty dielectric potting to withstand severe heat soak and prevent arcing. Paired with fine-wire iridium center electrode spark plugs, the system reduces the required firing voltage while delivering a hotter, more consistent spark. This ensures complete flame propagation, instant cold-start capability, and optimal combustion chamber pressure.
