RACE SPARK PLUG WIRE SET - EXTREME 9000 CERAMIC BOOT - LS TERMINALS LS3/LS4/LS7
This custom fit Race extreme heat ceramic boot ferro-spiral core spark plug wire set fits GM gen 4 LS3/LS4/LS7 engines.
Do you have problems cooking the spark plug wires on your LS based race engine? Do you need that extra assurance of not having a misfire due to a burnt spark plug wire during a race? If you answered yes to any of the previous questions, ACCEL has the wire set for you.
ACCEL Extreme 9000 Ceramic Boot Wires feature ultra high-temperature, double silicone, 8mm, 500 ohms/ft Ferro-Spiral core wire developed for performance use. The wire is rated at 600 degrees Fahrenheit peak and the Ceramic boots withstand up to 2,000 degrees. These race wires also feature Mr. Gasket Inferno Shield Thermal Sleeving to increase the heat resistance of the wire to 1200 degrees Fahrenheit. The Inferno shield is held in place with a high temp heat shrink so you do not have to worry about the shielding moving. Great for running headers with close tolerances, an engine bay with little room or an application with high under-hood temps due to extreme racing conditions. ACCEL Extreme 9000 wires offer excellent energy delivery to the spark plugs through stainless steel spark plug terminals, while providing the highest level of RFI/EMI suppression.

These are being used on a 2005 GMC with long tube headers and Speedway tall valve covers with the integrated coil mounts. These keep the wires from making contact with the primary tubes.
