Ignition Coil and Iridium Spark Plugs for Lexus NX200t (2015-2017) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2017 Lexus NX200t

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces worn factory secondary ignition hardware on the 2015-2017 Lexus NX200t to restore peak combustion efficiency, eliminate boost-induced misfires, and stabilize engine idle.

The Stock Lexus NX200t Secondary Ignition Breakdown

Under the high-boost, dual-injection operating parameters of the twin-scroll turbocharged 8AR-FTS engine, factory pencil coils endure intense thermal stress and dielectric breakdown. Over time, high cylinder pressures force secondary voltage requirements higher, leading to internal epoxy breakdown, high-voltage flashover, and micro-arcing in the deep spark plug wells of the AGZ10 and AGZ15 chassis. Paired with progressive center electrode erosion on high-mileage spark plugs, the widened gap places excessive dwell stress on aging coils. The result is unburned fuel, sluggish throttle response, reduced turbo efficiency, and recurring high-load misfire trouble codes (P0300–P0304).

The Engineering Solution

This direct replacement service kit includes four high-dielectric pencil ignition coils and four fine-wire iridium spark plugs engineered to withstand forced-induction heat soak. The coils feature high-conductivity copper windings insulated with premium epoxy potting compound to prevent high-voltage leakage under full boost. The accompanying iridium plugs utilize a high-density ceramic insulator and a laser-welded ultra-fine center electrode, significantly reducing quenching effects while optimizing spark kernel propagation. Designed as a precise match for OEM part numbers 90919-02269 and UF916, this kit restores crisp throttle modulation and reliable flame-front propagation without ECU modifications.
