Description

Spark plug boot failure is a silent killer on the track and street—heat, abrasion, and vibration degrade standard insulation, leading to misfires and performance loss. The Fire Sleeve Plug Boot 2523 wraps your ignition system in braided fiberglass protection, shielding against extreme underhood temperatures and mechanical stress while maintaining crisp spark delivery. For serious builds where every cylinder counts, this is cheap insurance against electrical gremlins.
