Heat Sleeves ASCAGHS-PR
These 18" long, 100% modacrylic, double layer heat sleeves are able to withstand up to 600°F and
are manufactured with thumb holes for a more secure fit.

Spark Plugs
Autolite Spark Plugs use a copper center electrode sheathed in nickel chromium alloy to provide superior heat dissipation.
A multi-rib insulator reduces the chances of “flash-over”, and a longer insulator, pioneered by Autolite, resists carbon fouling,
allowing combustion deposits to burn away. We carry a complete selection of plugs for virtually any application. Please call for
more details. Refer to spark plug reference chart on page 671.
