Ignition Coil + Spark Plugs for Nissan 240SX Sentra (1991-1994) 1.6L 2.4L

Direct-Fit Ignition Coil and Spark Plug Kit for 1991-1994 Nissan 240SX and Sentra (S13 / B13)

What it Does: The Ignition Coil and Spark Plug Kit restores primary spark energy and precise combustion timing to the 1991-1994 Nissan 240SX and Sentra to eliminate misfires, rough idle, and unburned fuel delivery.

The Stock Nissan Secondary Ignition Breakdown

Aging factory ignition components on the KA24DE and GA16DE platforms are notoriously vulnerable to high thermal cycles and breakdown of internal epoxy insulation. Over decades, the factory coil develops micro-fractures in the casing, resulting in secondary voltage leakage, carbon tracking, and coil heat soak that manifests as high-RPM misfires or hard-start conditions. Concurrently, factory spark plugs suffer from eroded center and ground electrodes, widening the plug gap beyond OEM tolerance. This increased resistance forces the aging coil to draw excessive primary current, leading to weak spark kernel propagation and incomplete fuel atomization across the cylinder head.

The Engineering Solution

This direct-replacement ignition pack upgrades your ignition baseline with a high-dielectric epoxy-molded ignition coil engineered to resist thermal degradation and internal short circuits. The precision-wound primary and secondary copper windings ensure stable inductive discharge, delivering a consistent high-voltage arch directly to the distributor circuit. Paired with 4 matched, pre-gapped spark plugs featuring durable nickel-alloy or copper cores and high-grade alumina silicate ceramic insulators, this kit stabilizes dwell angle response, suppresses electromagnetic interference (EMI), and provides clean, complete combustion under full-load conditions.

Frequently Asked Questions

Does this fit the S13 and B13 240SX and Sentra?
Yes, this is a direct fit for the 1991-1994 Nissan 240SX and Sentra equipped with the KA24DE and GA16DE engines.

Are spark plug wires included in this refresh package?
No, this kit includes one external ignition coil and four spark plugs; spark plug wires must be inspected and purchased separately if high resistance is found.

The Nissan JDM Heritage Standard

Golden-era Nissan inline-four powerplants depend entirely on crisp spark delivery to maintain sharp throttle response and linear power output. Refreshing the secondary ignition restores reliable, high-RPM combustion and sharp throttle pickup, keeping your classic S-Chassis or B-Chassis running true to its factory JDM performance pedigree.
