Product Details

The ACDelco 21025103 Spark Plug Boot Kit is a high-quality ignition system replacement component designed to restore proper electrical connection between your spark plug wires and spark plugs. Worn or cracked boots are a common cause of misfires, rough idle, and ignition failure — making timely replacement essential for optimal engine performance.

Key Features:

  • Weather-tight seal helps protect the spark plug connection from moisture intrusion and corrosion
  • High-temperature resistant silicone construction guards against thermal degradation in the harsh under-hood environment
  • Durable insulating material prevents voltage leakage and cross-firing between cylinders
  • Precision fit ensures a secure, rattle-free connection to the spark plug terminal
  • Manufactured to meet OE specifications for fit, form, and function
  • Backed by General Motors as part of the ACDelco parts family

ACDelco spark plug boot kits are engineered to deliver the same reliability as the original factory components. Whether you're restoring ignition performance or completing a full tune-up, the ACDelco 21025103 is a dependable, direct-replacement solution for a wide range of GM and compatible applications.
