FAST XR Series coils for GM LS engines offer 15 to 20 percent more spark energy than stock coils. They are constructed from premium, ultra-pure copper alloy windings, resulting in firing performance approaching 50,000 peak volts. Tested to 8,000+ rpm and almost 1,500 hp, these ignition coils have been proven to perform in some of the harshest street and race engine environments. Designed for all popular generations of GM LS engines, the FAST XR Series coils are ideal for any street or racing application where reliable, powerful ignition output is needed.
