Ford F-150/F-250: Coil Reviews

This article applies to the Ford F-150 (2004-2014) and F-250, F-350 Super Duty (2005-2014).

Ignition coils play an important role in your Ford truck's electrical system, transforming the low voltage provided by a battery into the higher voltage needed to create a spark in spark plugs strong enough to ignite fuel. If your coils are going bad, you may notice a dip in the RPM when the truck is at idle or a check engine light that turns on and off intermittently. If you have a high performance application, installing high performance aftermarket coils can help provide the extra spark that you need over stock coils. Here we will take a look at three of the more popular aftermarket options available for the F-150 and Super Duty.

Accel coils cost a bit more than stock options, but many forum members report an increase in performance and longer life. Accel makes coils for performance applications, but even a stock truck can get a nice boost from a set. Pricing is actually lower in some instances than other brands such as Motorcraft, but you will get a little more performance and an increase in fuel economy by installing a set of Accel coils. Recommended if you are looking for performance.

Jegs

Jegs coils provide great value with an increase in performance over stock coils. Jegs claims that these coils provide a 15-20% increase in spark energy over stock coils in an F-Series truck. These, like our other examples, provide gains in fuel economy, performance, and throttle response. They are a more economical choice than Motorcraft coils, but offer similar performance. Forum users have a good overall opinion on Jegs coils, touting their reliability and quality for the price. Recommended if you are looking for a better than factory coil for the best price.

Motorcraft

Motorcraft coils, much like all of their parts, have a good reputation among users on forums. Most users report long life and improved gas mileage, power, and throttle response after installing a set of Motorcraft coils over a set of stock or worn coils. An added benefit is knowing that Motorcraft coils are manufactured by Ford to fit the exact measurements and requirements of your F-150. Recommended if you are looking for longest life and gas mileage.
