    • Product Type: Boot
    • Sub Category: Ignition Wire and Related Components
    • Feature: Cylinder numbers printed on sleeving
    • Warranty: Manufacturer's Limited 1-Year Warranty

    Slide over the connection and apply heat to shrink it into place.

    FAQ

    What makes the 3415 sleeve different from a standard shrink sleeve?

    It is printed with cylinder numbers so each spark plug wire is clearly identified.

    How is it installed?

    It slides over the spark plug boot or connection and shrinks tightly into place once heat is applied.

    Why would cylinder-numbered sleeving matter for racing?

    It prevents confusion about which wire goes where during quick wire changes in the pits.
