Mopar Performance 68166329AA Spark Plug Tube Seal

The Mopar Performance 68166329AA is a genuine OEM spark plug tube seal designed to prevent oil leakage around spark plug tubes in Chrysler, Dodge, Jeep, and Ram engines. This critical seal creates a tight barrier between the valve cover and spark plug tube, preventing oil from seeping into the spark plug wells where it can cause misfires, fouling, and potential engine damage.

Key Features:

• Genuine Mopar OEM part ensures exact fit and reliable performance
• Prevents oil contamination in spark plug wells
• High-temperature resistant seal material withstands engine heat
• Direct replacement for worn or leaking original seals
• Helps maintain optimal ignition system performance

Oil leaking past worn spark plug tube seals is a common issue on many Mopar engines, particularly HEMI V8s and Pentastar V6 engines. Replacing these seals during valve cover gasket service or when addressing oil in spark plug tubes will restore proper sealing and prevent recurring ignition problems. This seal is sold individually, so order the appropriate quantity for your engine configuration.
