United Motor Products 908S Coil-on-Plug boot Spring kit assemblies - 3

The United Motor Products 908S is a direct-fit coil-on-plug (COP) boot and spring kit containing three complete assemblies. Designed as an OEM-quality replacement for the ignition system, this kit restores reliable electrical contact between the ignition coil and spark plug on applicable 6-cylinder engines.

Key Features:

• Includes 3 coil-on-plug boot and contact spring assemblies
• Replacement boots are manufactured to OEM specifications using high-temperature resistant materials
• Contact springs are precisely wound to maintain correct resistance ratings and ensure consistent coil operation
• Boots seal the coil-to-spark-plug interface, preventing voltage leakage, moisture intrusion, and debris contamination
• Direct replacement design simplifies installation with no modification required
• Dielectric grease included for ease of installation and long-term connection protection

Worn or cracked coil-on-plug boots are a common cause of ignition misfires, rough idle, and poor fuel economy. Replacing the boots and springs restores proper high-voltage insulation and spark delivery, helping eliminate misfires and protecting the coil from premature failure.
