Ignition Coil + Spark Plugs for Nissan Altima (1993-1997) 2.4L

Direct-Replacement Ignition Coil and Spark Plug Kit for 1993-1997 Nissan Altima (U13)

What it Does: The ignition coil and spark plug kit replaces degraded primary ignition components on the 1993-1997 Nissan Altima to restore factory combustion efficiency, eliminate secondary voltage leaks, and smooth rough engine idle.

The Stock Nissan Altima Ignition Breakdown

The first-generation U13 chassis relies on an external ignition coil setup paired with a distributor to route secondary voltage to the KA24DE combustion chambers. Decades of engine bay thermal cycling degrade the internal copper windings and epoxy resin insulation of the factory coil, leading to core saturation breakdown, dielectric punch-through, and intermittent misfires under load. Compounding this, worn spark plugs exhibit eroded nickel electrodes and widened gaps, which spikes the secondary voltage requirement, overworking the ignition coil and causing hesitations, poor fuel economy, and unburnt hydrocarbon emissions.

The Engineering Solution

This direct-fit ignition refresh kit resolves high-voltage transfer loss by pairing a robust external ignition coil with four matched spark plugs. The replacement coil utilizes premium magnetic copper wire windings and high-dielectric epoxy potting to handle thermal stress without arc-over or insulation failure. Matched to factory heat ranges, the included spark plugs feature anti-corrosive plating, high-alumina ceramic insulators, and precision-gapped ground electrodes. This setup guarantees stable arc delivery across the full RPM band, preventing quench-out and restoring consistent cylinder pressures.
