Engineered specifically for 5.7L single-plug Chrysler Hemis, this 8-pack of highly conductive direct-plug replacement coils give you 10-15 percent more power, reduce misfire, and eliminate hesitation and stumble at medium speeds. Smaller, lighter, and more powerful than existing coils, they have specially designed silicon-magnetic steel E-cores with optimized low-resistance windings. They're effortless to install, and their high-temperature epoxy construction resists shock and vibration while increasing thermal conductivity. These innovative, completely redesigned SuperCoils are the total package: you'll have more power, more torque, quicker starts, instant throttle response, noticeably better acceleration, a smoother idle, and even better gas mileage.

Very straight forward install, took me about 2 hours. The 2 coils against the firewall were a little tricky. I'm also running 9mm Taylor wires, S&B intake, and a superchips programmer on my 05 Ram 5.7L Hemi. As a complete package the truck runs strong! Definitely noticed some power gains and much better throttle response. So far so good with the coils!

Coils state they are direct swap with no modifications necessary. I installed and got very poor idle and constant stalling a low RPM. Re-installed OEM coils and problem went away. I replaced because my engine has 105,000 miles, just as a complete tune-up, but they did not work in my car: 05 dodge magnum 5.7 Seller did give a prompt and complete refund.
