Comparison Insights for Ram 1500 Ignition Coils
Choosing the right set depends entirely on your engine and needs. Here are a few quick observations on how these options stack up:
- Engine Type is Key: If you have the popular 5.7L Hemi V8, you need the UF504 type (A-Premium, Pack of 8, Dragon FIRE, ENA UF504). If you have the older 4.7L V8, you must select the UF270 type (ENA 4.7L set).

Best Ignition Coil For Ram 1500 FAQ
What are the main signs that my Ram 1500 ignition coils need replacement?
The most common symptoms include engine misfires (often felt as hesitation or sputtering during acceleration), rough or inconsistent idling, a sudden drop in fuel economy, and the Check Engine Light illuminating (often triggering a P030X code indicating a specific cylinder misfire). If your Ram 1500 is running poorly after 80,000 to 100,000 miles, coils are a likely suspect.
Is there a difference between ignition coils for the 4.7L V8 and the 5.7L Hemi engine?
Yes, absolutely. The design, mounting bracket, and electrical connections are different between the two engine families. The Hemi (5.7L) typically uses the UF504 style coil pack, while the older 4.7L V8 requires the UF270 style. Installing the wrong type will not work and could damage your vehicle’s wiring harness.
Should I replace all 8 ignition coils at once, or just the failed one?
While you can theoretically replace just the failed coil pack, most mechanics strongly recommend replacing all 8 at once, especially if your truck has high mileage. Ignition coil packs tend to wear out at similar rates. Replacing them as a complete set ensures consistent voltage across all cylinders, preventing future misfires and keeping your Ram 1500 Hemi performance optimized.
Do aftermarket ignition coils perform better than OEM coils?
It depends on the quality. High-quality aftermarket coils, such as those with performance-grade copper windings (like Dragon FIRE), often meet or slightly exceed OEM output specifications, leading to a stronger spark. However, cheap, low-quality aftermarket coils may fail faster than OEM. When selecting the best ignition coil for Ram 1500, always choose a reputable brand with a good warranty.
What spark plug gap should I use with new ignition coils on a 5.7L Hemi?
For a stock 5.7L Hemi Ram 1500, the standard spark plug gap is typically between 0.043 inches and 0.045 inches. Always confirm the exact specification in your owner’s manual, or look up the requirement based on your specific model year, as incorrect gapping can reduce the efficiency of even the best ignition coil for ram 1500.
Are ignition coil packs difficult to install on a Ram 1500?
Replacing ignition coils on a Ram 1500 is generally considered an easier DIY maintenance task. On the Hemi engine, the coils are readily accessible on top of the valve covers, secured by a few bolts. You will need basic hand tools and about an hour or two to complete the job, making this an ideal way to improve Ram 1500 engine performance yourself.
