      Improve Your Ignition Responsiveness. A good ignition system is crucial for a Wrangler, especially when off-roading. But like everything else, spark plugs won’t last forever. If it’s time to make some adjustments to your ignition system, the RC12ECC Spark Plug is a good start. It’s made by Crown Automotive as a direct replacement upgrade, and a couple of these bad boys can breathe new life into your Wrangler’s ignition system.

      Quality Design. The ceramic and copper combination makes the RC12ECC Spark Plug extremely responsive and capable of improving your Jeep’s throttle. This high-performance piece uses the best materials and engineering to revitalize engines, improve spark reliability, and endure stressful situations without stalling.

      Straightforward Installation. The RC12ECC Spark Plug by Crown Automotive will work on both 2.5L and 4.0L engines. Replacing malfunctioning or underperforming spark plugs with this model can be done without any adaptation or advanced mechanical skills. However, do remember to unplug the battery before making any replacements. Safety first!

      Limited Warranty. With Crown Automotive, you always get a minimum of 12 months of coverage for aftermarket replacement upgrades. The RC12ECC Spark Plug is no exception, as it will be covered against workmanship imperfections and material flaws for the same duration.

      Application. The RC12ECC Spark Plug matches the spark plugs on the 1999-2006 Jeep Wrangler TJ 2.5L and 4.0L models.
