Ignition Coil and Iridium Spark Plugs for Honda CR-V (2017-2021) 1.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Tune-Up Kit for 2017-2021 Honda CR-V

Direct Ignition Refresh: Replaces failing factory coil packs and eroded spark plugs to restore crisp throttle response, clean combustion, and smooth idle across all driving conditions.

The Stock CR-V High-Boost Thermal Degradation

The direct-injected 1.5L turbocharged Earth Dreams engine generates high cylinder pressures and elevated under-hood temperatures. Over time, OEM ignition coils suffer from dielectric breakdown, internal primary and secondary winding degradation, and thermal hardening of the silicone boot. Paired with standard spark plug electrode erosion, the expanded gap demands excessive firing voltage, causing intermittent misfires (P0300–P0304 codes), rough idle, power hesitation under boost, and decreased fuel economy.

The Precision Engineering Solution

This kit combines high-grade replacement ignition coils with premium fine-wire iridium spark plugs designed specifically for forced-induction direct-injection demands. The ignition coils feature heat-resistant epoxy resin potting and high-conductivity copper wiring to prevent internal shorting and voltage drop. The matched iridium plugs feature laser-welded fine-wire center electrodes and platinum ground surfaces, resisting carbon fouling and high-boost flame quenching while lowering the required firing voltage for consistent, complete combustion.
