Ignition Coil and Iridium Spark Plugs for Lexus RC200t (2016-2017) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2017 Lexus RC200t

What it Does: The ignition coil and iridium spark plug kit restores factory combustion efficiency, eliminates cylinder misfires, and stabilizes idle on the 2016-2017 Lexus RC200t.

The Stock Lexus RC200t Ignition Breakdown

The forced-induction 8AR-FTS engine in the ASC10 chassis operates under high combustion pressures and severe thermal loads. Over extended heat cycles, factory pencil coils succumb to internal dielectric breakdown and insulation fatigue. Paired with inevitable electrode erosion on aging spark plugs, the widened gap demands higher firing voltage that compromised coils cannot provide. This results in hesitation under boost, rough idle, poor fuel economy, and diagnostic trouble codes such as P0300 through P0304.

The Engineering Solution

This direct-fit service kit replaces tired hardware with four high-dielectric pencil ignition coils and four fine-wire iridium spark plugs. The coils feature heat-resistant epoxy potting and reinforced silicone boots to withstand localized turbocharger heat soak and prevent secondary voltage leakage. The fine-wire iridium center electrodes provide concentrated spark discharge with lower required primary voltage, maintaining flame-front stability under peak manifold boost pressures to guarantee clean combustion.
