Ignition Coil and Iridium Spark Plugs for Acura MDX (2010-2013) 3.7L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2010-2013 Acura MDX

Direct-fit tune-up kit: Restores factory secondary ignition voltage and combustion efficiency across all six cylinders on J-series V6 powertrains.

The Stock MDX Thermal Breakdown and Spark Degradation

Under sustained underhood heat cycling, factory coil-on-plug epoxy insulation breaks down, causing internal micro-arcing, secondary winding resistance drift, and high-rpm misfires. Concurrently, standard electrode erosion widens plug gaps, forcing aging coils to operate beyond their designed duty cycle, triggering hesitation and P0300-P0306 diagnostic trouble codes.

The Engineering Solution

This comprehensive service kit pairs six high-dielectric coil packs featuring high-grade internal copper windings with six pre-gapped, corrosion-resistant iridium-tipped spark plugs. High-purity copper windings ensure sustained primary-to-secondary step-up voltage under load, while fine-wire iridium center electrodes lower ignition system voltage demand, stabilizing idle quality and ensuring complete air-fuel burn.
