Ignition Coil and Iridium Spark Plugs for Mazda CX-5 (2013-2018) 2.0L 2.5L

High-Dielectric Ignition Coil and Iridium Spark Plug Kit for 2013-2018 Mazda CX-5

Direct-Fit Ignition Overhaul: Restores factory combustion efficiency, eliminates cylinder misfires, and resolves rough idle across high-compression SkyActiv-G powertrains.

The Stock CX-5 SkyActiv Ignition Breakdown

Direct-injection SkyActiv-G engines operate under extreme 13.0:1 to 14.0:1 compression ratios, subjecting factory pencil coils to severe thermal stress and dielectric breakdown. Over time, OEM coil boots degrade from under-hood heat cycling, inducing micro-arcing and secondary voltage leakage. Paired with worn spark plug electrode gaps, this deterioration leads to hesitation under load, erratic idle, delayed throttle response, and P0300–P0304 misfire codes.

The Engineering Solution

This complete ignition service kit features high-dielectric epoxy-molded pencil coils engineered to resist thermal degradation and prevent high-voltage flashover. Matched with fine-wire DILKAR7G11GS iridium spark plugs, the assembly delivers reliable high-energy spark discharge with minimal flame quenching. The wear-resistant iridium center electrode maintains precise gap tolerances under high cylinder pressures, restoring crisp throttle response and stabilizing combustion dynamics.
