Wake Up Your Sleeping Gen III Hemi with FAST XR Series Ignition Coils
Around 40,000 volts of spark energy should get your 2006-19 Gen III Hemi up in the morning. FAST XR Series Ignition Coils provide just that, which is 15 percent more spark energy than the factory coils make.
The XR Series coils are direct replacements for the factory coils and have premium, ultra-pure copper alloy windings to deliver a reliable, powerful spark to help your engine perform at its peak. They’re emissions-legal in all 50 states and can be installed without any additional modifications.
Summit Racing also carries FAST XR Series Ignition Coils for GM LS, Ford Modular V8, and Ford 3.5L EcoBoost engines.
