Ignition Coil and Iridium Spark Plugs for Toyota 86 (2017-2020) 2.0L

OEM-Grade Ignition Coil and Iridium Spark Plugs for 2017-2020 Toyota 86

This complete ignition service kit replaces worn factory ignition coils and spark plugs to restore proper combustion, eliminate misfires, and stabilize idle on the FA20 engine.

The Stock ZN6 Ignition Shortcoming

The factory ignition coils and spark plugs on the 2.0L FA20 engine are subjected to extreme under-hood temperatures due to the horizontally opposed "boxer" layout. Over time, this intense thermal cycling breaks down the epoxy resin inside the factory ignition coils, leading to internal voltage leaks. Concurrently, standard or worn spark plug electrodes degrade, widening the spark gap. This combination results in weak spark delivery, manifesting as rough idling, hesitation under heavy throttle loads, increased emissions, and cylinder misfires—especially noticeable during high-RPM pulls where the ignition system operates at maximum duty cycle.

The Engineering Solution

Upgrading to this matched set of ignition coils and iridium spark plugs directly resolves FA20 ignition failure points. The replacement coils are wound with high-conductivity copper wire and housed in high-dielectric epoxy resin to resist high-temperature degradation, preventing voltage tracking and thermal breakdown. Paired with iridium spark plugs, which feature an ultra-fine center electrode and superior melting point compared to standard platinum or copper plugs, this kit ensures a concentrated, powerful spark. The iridium construction requires less voltage to bridge the spark gap, reducing the strain on the new coils while promoting complete fuel burn, maximizing the engine's volumetric efficiency, and restoring crisp throttle response across the RPM band.
