Ignition Coil & Iridium Spark Plugs for Lexus LX570 (2008-2020) 5.7L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2008-2020 Lexus LX

Restores engine efficiency and eliminates misfires by delivering a consistent, high-voltage spark to the combustion chamber of the 3UR-FE V8.

The Stock LX Thermal Degradation Issue

The OEM ignition system on the URJ200-generation LX 5.7L is highly susceptible to thermal degradation over extended, high-mileage heat cycles. Continuous exposure to the 3UR-FE's radiant engine temperatures causes the factory coil boots to become brittle, leading to micro-cracking and parasitic voltage leaks. This degradation results in intermittent misfires, a rough idle, reduced towing capacity, and a noticeable drop in fuel economy. Furthermore, worn standard or platinum plugs exacerbate the issue by widening the spark gap, which forces the coils to demand higher secondary voltage, ultimately accelerating primary component failure.

The Engineering Solution

This comprehensive ignition kit features eight precision-wound ignition coils engineered with high-dielectric epoxy and thermal-resistant silicone boots. This robust construction prevents voltage bleed and ensures reliable operation under extreme under-hood temperatures. Paired with eight Iridium-tipped spark plugs, the system requires less firing voltage while delivering a more concentrated spark kernel. The ultra-fine iridium center electrode resists spark erosion, maintaining a precise gap over tens of thousands of miles. This synergy maximizes combustion efficiency, eliminates hesitation during heavy-throttle inputs, and restores factory-level power delivery and smooth idling dynamics.
