Ignition Coil and Iridium Spark Plugs for Mitsubishi Lancer (2008-2017) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2008-2017 Mitsubishi Lancer

What it Does: This complete ignition service kit replaces degraded OEM ignition coils and worn plugs to restore factory dwell timing, prevent cylinder misfires, and stabilize combustion across the entire RPM range.

The Stock Lancer 4B11 Ignition Breakdown

Over extended heat cycles, factory 4B11 coil packs suffer internal dielectric breakdown within their secondary epoxy windings. Thermal degradation increases internal electrical resistance, which reduces peak spark voltage and slows spark discharge time. Paired with aged, gap-eroded factory plugs, this drop in ignition energy causes hesitation under wide-open throttle, rough cold-start idling, and unburned fuel loading downstream catalytic converters.

The Engineering Solution

Engineered to exact OEM specifications, these direct-fit ignition coils utilize high-grade internal copper windings and high-dielectric potting compound to resist thermal fatigue and prevent voltage punch-through. The included fine-wire iridium spark plugs provide superior spark concentration, lower required firing voltage, and elevated resistance to electrical erosion compared to standard nickel cores. The result is rapid flame-front propagation, consistent high-RPM spark delivery, and crisp throttle response.
