Description
Spark plug boots are exposed to extreme underhood heat, vibration, and potential contact with exhaust manifolds—degradation here means misfires and unreliable ignition timing when you need precision most. These braided fiberglass sleeves add a thermal barrier that extends boot life and protects against premature cracking, arcing, and performance loss. Whether you’re running a street car or pushing boost on the track, this is practical insurance for a critical ignition component.
