Ignition Coil and Iridium Spark Plugs for Toyota RAV4 (2004-2008) 2.4L

Direct-Fit High-Conductivity Ignition Coil and Iridium Spark Plug Kit for 2004-2008 Toyota RAV4

Primary Function: Restores complete cylinder combustion and sharpens throttle response by replacing degraded factory coil-on-plug packs and worn spark plugs in 2.4L Toyota powertrains.

The Stock RAV4 Ignition Breakdown

Factory ignition coils on the 2.4L 2AZ-FE engine endure continuous thermal cycling within the cylinder head recess. Over time, internal epoxy insulation degrades and high-tension copper windings experience micro-fractures, leading to secondary winding breakdown, high-rpm misfires, rough idle, and unburned fuel entering the catalytic converter. Simultaneously, standard nickel or worn factory plugs suffer gap erosion, increasing required secondary voltage and accelerating coil failure.

The Engineering Solution

This complete tune-up package features four coil-on-plug assemblies engineered with high-density internal copper windings and reinforced dielectric housings to resist dielectric breakdown under extreme thermal loads. Paired with fine-wire iridium spark plugs, this setup lowers ignition voltage demand, stabilizes spark kernel formation, and delivers clean combustion across the power band.
