Ignition Coil & Iridium Spark Plugs for Toyota Camry (2007-2017) 3.5L V6

High-Output Ignition Coil & Iridium Spark Plugs for 2007-2017 Toyota Camry (2GR-FE / XV40, XV50)

Direct replacement ignition coil and iridium spark plug kit designed to restore misfire-free combustion, optimize fuel burn, and stabilize idle across the RPM range.

The Stock Camry Ignition Weakness

OEM ignition coils on the 2GR-FE engines are highly susceptible to thermal degradation over high mileage. Positioned deeply within the cylinder head and subjected to constant, severe heat soak from the transverse V6 layout—especially the firewall-facing rear bank—the factory epoxy potting degrades over time. This thermal cycling leads to micro-cracking in the coil housing, internal arcing, and subsequent voltage drops. Concurrently, factory standard spark plug electrodes erode, increasing the gap and demanding higher voltage to bridge the spark. This cascading failure results in dreaded P0300-series misfire codes, sluggish throttle response, parasitic power loss, and unburnt fuel entering the exhaust stream, which can prematurely foul the catalytic converters.

The Engineering Solution

This complete ignition overhaul kit resolves these inherent factory deficiencies by pairing high-performance iridium spark plugs with upgraded ignition coils. The coils feature high-grade dielectric epoxy and reinforced polymer housings engineered to withstand severe thermal cycling without cracking or failing. Enhanced primary and secondary copper wire windings increase energy transfer, delivering a hotter, more consistent spark. Mated to the ultra-fine wire iridium center electrodes of the included spark plugs, the system requires less firing voltage while producing a highly stable and concentrated spark kernel. This engineered synergy ensures optimal combustion chamber dynamics, resulting in complete fuel vaporization, restored factory power output, smoother idle, and reliable long-term engine operation under heavy engine loads.
