Ignition Coil & Iridium Spark Plugs for Toyota Land Cruiser (2008-2020) 5.7L V8

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2008-2020 Toyota Land Cruiser

Restores lost ignition efficiency and eliminates misfires on the J200 Land Cruiser 5.7L V8. This comprehensive 8-pack of ignition coils and iridium spark plugs delivers consistent spark energy to optimize combustion and resolve common high-mileage stuttering issues.

The Stock Land Cruiser Ignition Weakness

The factory Toyota 3UR-FE 5.7L V8 is a legendary workhorse, but its original ignition coils are notorious for thermal degradation over time. Subjected to relentless heat cycling deep within the engine bay, the internal epoxy potting breaks down, leading to micro-arcing and voltage leaks. This typically manifests as intermittent misfires under heavy load, rough idling, and a noticeable drop in fuel economy. Furthermore, aging standard or worn spark plugs widen the gap, increasing resistance and forcing the ignition coils to work harder, accelerating failure and eventually triggering a P0300-series CEL.

The Engineering Solution

This ignition replacement kit engineered specifically for the J200 chassis tackles these thermal constraints head-on. The ignition coils feature high-dielectric epoxy resin and upgraded copper wire windings to maximize voltage output while resisting heat-induced internal shorts. Paired directly with premium iridium-tipped spark plugs, the system requires less firing voltage to bridge the gap, effectively reducing electrical strain on the primary coil windings. The ultra-fine iridium center electrode concentrates spark energy for a more complete burn, eliminating misfires under heavy towing conditions, enhancing throttle response, and stabilizing idle RPMs back to factory specifications.
