Ignition Coil & Iridium Spark Plugs for Toyota Venza (2009-2015) 2.7L I4

Performance Ignition Coil & Iridium Spark Plug Kit for 2009-2015 Toyota Venza (1AR-FE / AGV10)

What it does: This direct-replacement ignition coil and iridium spark plug kit resolves misfires, restores proper voltage delivery, and improves combustion efficiency for the 2.7L 1AR-FE engine.

The Stock Venza Ignition Shortcomings

The factory ignition coils on high-mileage 1AR-FE engines are prone to thermal degradation and dielectric breakdown. Constant heat cycling within the transverse engine bay accelerates the deterioration of the internal epoxy potting and primary windings. This leads to weakened spark energy, increased electrical resistance, and erratic spark timing. Paired with worn stock plugs, the result is poor atomization, delayed flame propagation, rough idling, hesitation under load, and reduced fuel economy.

The Engineering Solution

This kit pairs high-output ignition coils with performance iridium spark plugs to maximize spark kernel intensity. The coils feature upgraded copper wire windings and high-temperature epoxy to resist thermal shock and electrical arcing. The iridium center electrodes provide a microscopic, concentrated spark area that requires less firing voltage while resisting erosion far better than traditional materials. This promotes complete combustion, resulting in restored torque, smoother idle stability, and optimal fuel burn across the entire RPM range.
