Description
High heat and electrical interference degrade spark plug boots over time, causing misfires and unreliable ignition timing—especially critical in forced-induction and high-RPM LS applications. KoolSox braided fiberglass sleeves insulate your boots from under-hood heat while shielding against EMI, protecting your ignition system and maintaining consistent spark delivery. This 8-pack covers a complete LS engine, making it an essential upgrade for any serious build.
