Quick facts

• Part: Bosch 6766 spark plug
• Fits: 2021-2026 Jeep Wrangler V8 6.4L and other vehicles
• Condition: New

A worn spark plug can show up as hard starting, a rough idle or a misfire. Faults elsewhere in the ignition or fuel system can look just like these, so find the cause before replacing spark plugs. With the engine off and cool, look at the electrode and ceramic of a removed plug for wear or damage; a shop can test the rest.
