Ignition Coil and Iridium Spark Plugs for Hyundai Tucson (2005-2009) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2005-2009 Hyundai Tucson

Direct-fit replacement: Restores complete combustion efficiency and eliminates cylinder misfires across the transverse 2.7L V6 powertrain by replacing tired ignition coils and worn plugs with high-dielectric components.

The Stock Tucson Thermal Breakdown

Factory ignition coils on the 2.7L V6 operate in a tightly packaged engine bay subject to severe thermal cycling. Over mileage, the factory epoxy and secondary windings suffer dielectric breakdown, leading to voltage leaks and insulation failure—particularly on the heat-trapping rear cylinder bank. Paired with aged, eroded copper or nickel spark plugs, the increased gap resistance overburdens the ignition system, causing hesitation under load, poor fuel economy, and catalytic converter damage.

The Engineering Solution

This comprehensive tune-up kit features six direct-fit ignition coils built with high-grade PBT thermoplastic housings and high-conductivity copper primary/secondary windings to prevent dielectric breakdown under sustained heat. Paired with laser-welded fine-wire iridium spark plugs, this kit provides a consistently focused ignition spark that requires lower firing voltage, prevents spark blow-out, and delivers superior thermal durability up to 4,000°F.
