Spark Hard with FAST XR Series Ignition Coils for GM LS

When it’s time to turn up the power, you’ll need a stronger spark. FAST XR Series Ignition Coils give your GM LS engine the spark energy required to light the densest air/fuel mixtures and make big power.

Featuring advanced, ultra-pure copper alloy windings and other premium internal components, XR Series coils generate 15-20 percent more spark energy—approaching 50,000 peak volts— than stock coils. The increased ignition output prevents misfires under load, improves combustion efficiency, and supports horsepower gains by ensuring a complete fuel burn.

FAST designed the XR Series Coils to thrive in harsh underhood environments too. Their durable construction withstands heat, vibration, and extended high-RPM use all the way up to 8,000-plus RPM and almost 1,500 horsepower. Installation is quick and hassle-free thanks to a direct-fit design and OE-style connections.

Other features include:
• Ideal for any application where reliable, powerful ignition output is needed
• Improved throttle response
• Enhanced idle quality and part-throttle drivability
• Maintains consistent power production throughout the entire RPM range

FAST XR Series Coils fit all generations of GM LS engines.
