Spark Plug for 2003-2006 Jeep Wrangler & More - Bosch 9654

Bosch 9654 spark plug for the 2003-2006 Jeep Wrangler 4-cylinder 2.4L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. This Bosch spark plug uses a double iridium design with a fine wire electrode.

• Bosch Double Iridium line with a laser welded, tapered ground electrode
• Iridium-alloy center electrode firing pin and a ground electrode inlay for long service life
• Fine wire design needs up to 24% less voltage to ignite
• 360 degree continuous laser welding for added durability
• Copper core gives a broader heat range that resists pre-ignition and fouling
