Ignition Coil & Iridium Spark Plugs for Jeep Wrangler Gladiator JL JT (2018-2026) 3.6L V6

Direct-Fit Ignition Coil & Iridium Spark Plugs for 2018-2026 Jeep Wrangler, Gladiator (Pentastar V6 / JL, JT)

Direct OEM replacement ignition kit: Restores factory spark intensity and engine efficiency by addressing misfires and rough idling, and degraded fuel economy common in high-mileage Pentastar V6 engines.

The Stock Wrangler & Gladiator Weakness

The factory ignition coils on the 3.6L Pentastar V6 are highly susceptible to thermal breakdown due to their proximity to the exhaust manifolds and sustained high-load driving scenarios like rock crawling or towing. Over time, internal winding resistance increases, severely dropping voltage output. Simultaneously, OEM spark plug electrodes wear down, widening the gap and increasing the electrical strain on the coils. This combination leads to intermittent misfires under heavy load, sluggish throttle response, and a noticeable drop in low-end torque exactly when it is needed on the trail.

The Engineering Solution

This comprehensive replacement kit utilizes upgraded ignition coils engineered with high-conductivity copper internal windings protected by a high-dielectric epoxy resin. This prevents thermal breakdown and high-voltage leaks under severe underhood temperatures. Paired with the included iridium spark plugs, the kit ensures a highly concentrated, stable spark arc. Iridium's extreme melting point resists gap erosion exponentially better than standard copper or platinum variants, providing precise ignition timing, a smoother idle, and consistent power delivery whether navigating steep, low-speed obstacles or accelerating on the highway.
