Ignition Coil and Iridium Spark Plugs for Mitsubishi Mirage (2014-2017) 1.2L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2014-2017 Mitsubishi Mirage

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces fatigued factory ignition components on the 2014-2017 Mitsubishi Mirage to eliminate high-rpm misfires, restore flame kernel propagation, and stabilize idle quality.

The Stock Mitsubishi Mirage Thermal Breakdown Problem

The compact 1.2L inline-three engine operates with tightly packaged pencil coils routed into narrow spark plug wells directly over the cylinder head. Over repeated thermal cycles, the factory internal copper windings and potting epoxy suffer dielectric breakdown. This insulation failure leads to secondary voltage leakage and carbon tracking down the boot. Compounding this, degraded factory plug gaps increase electrical resistance, over-saturating the coils and causing cylinder-specific misfire codes (P0300–P0303) across the A03A chassis.

The Engineering Solution

This complete ignition refresh kit pairs reinforced coil-on-plug assemblies with durable iridium spark plugs. Each pencil coil features premium copper wire windings insulated in vacuum-poured dielectric epoxy to withstand extreme underhood temperatures without degradation. Heavy-duty fluorosilicone boots lock out moisture and resist oil fouling in deep plug wells. Paired with laser-welded fine-wire iridium center electrodes, the kit lowers ignition voltage requirements, optimizes thermal clearance, and guarantees stable arc generation under lean air-fuel conditions. Replaces OEM part numbers 1832A057 and UF815.
