Ignition Coil + Spark Plugs for Mazda Millenia (1995-2002) 2.3L

Direct-Replacement Ignition Coil & Spark Plug Kit for 1995-2002 Mazda Millenia 2.3L (TA / KJ-ZEM)

What it Does: The ignition coil and spark plug kit replaces degraded OEM ignition hardware on the 1995-2002 Millenia 2.3L to eliminate high-load misfires, stabilize idle, and restore consistent spark delivery under boost.

The Stock Mazda Millenia Ignition Breakdown

The Miller-cycle KJ-ZEM operates under constant positive manifold pressure via its factory Lysholm twin-screw supercharger, subjecting the ignition system to extreme cylinder pressures. Over prolonged heat cycles in the tightly packed TA engine bay, factory coil epoxy degrades and internal secondary copper windings short out. Coupled with widened electrode gaps on aged spark plugs, this thermal breakdown induces secondary voltage leakage, resulting in hesitations, unburned fuel wash, and persistent P0300-P0306 misfire trouble codes under acceleration.

The Engineering Solution

Engineered for high-duty forced induction conditions, this complete refresh kit utilizes reinforced thermoplastic coil-on-plug housings vacuum-potted in premium dielectric epoxy to combat heat soak and arc-through. High-conductivity magnetic wire windings deliver stable, high-energy kilovolt output directly to factory-matched plugs, eliminating spark blowout under boost. Direct OE terminal integration ensures a plug-and-play install without harness modification, restoring crisp throttle response and clean combustion cycles.
