ENA Set of 8 Straight Boot Ignition Coil Pack Compatible with Ford Lincoln Expedition Explorer F-150 Super Duty Mustang Mountaineer 4.6l 5.4l Replacement for DG511 C1541 FD508

The ENA DG511 replacement set is a highly popular option for the later 5.4L Triton engines that require the straight, black coil boots. This plug-and-play kit offers factory-like fitment and is specifically engineered to ensure consistent spark output, directly addressing common misfire issues associated with aged original equipment. If your truck was manufactured after late 2004, especially F-150s, this set offers excellent quality without the steep OEM price tag, bringing back smooth idling immediately after installation.

Key features that stand out:
– Exact DG511 Replacement: Specifically designed for vehicles requiring the black coil boots.
– Wide 5.4L Compatibility: Fits many popular models like the F-150, Expedition, and Navigator from the mid-2000s.
– Durable Construction: Built with materials resistant to high heat and vibration common in the engine bay.

Pros:

Helpful Comparison Short Insights

When evaluating the best ignition coil for 5.4 triton, the most crucial decision is the application type: DG508 (Curved Boot) vs. DG511 (Straight/Black Boot).

For Older 5.4L Engines (Pre-2004 DG508/Curved Boot):
If you have an older F-150 or Expedition, you need the DG508/Curved Boot. The ENA Curved Boot Set stands out because of its commitment to quality backed by a lifetime warranty, providing the highest reliability assurance. If you also need spark plugs, the MAS DG508 Combo with Motorcraft Plugs is the best comprehensive maintenance option.

For Newer 5.4L Engines (2004+ DG511/Straight Boot):
The switch to the DG511 (straight black boot) generally occurred around 2004. For these trucks, the ENA Straight Boot Set offers fantastic value and OEM-level replacement quality. If you are doing a full tune-up, the Ignition Coil Pack & Spark Plugs (DG511 Combo) offers the convenience of pre-gapped plugs delivered in one package.

Performance vs. Reliability:
While the LCWRGS DG508 Set claims a 15% energy boost, if raw, long-term dependability is your primary goal, products like DRIVESTAR and the ENA Lifetime Warranty units focus more heavily on high heat tolerance and proven materials for endurance.

Final Verdict

Choosing the best ignition coil for 5.4 triton hinges on your truck’s specific year and your budget. Here are my top recommendations based on testing insights:

Top Choice for Reliability (DG508/Older Models):
The ENA Set of 8 Curved Boot Ignition Coil Pack wins for reliability thanks to its impressive lifetime warranty. When dealing with the 5.4L Triton, that warranty coverage against heat failure is worth the investment.

Top Choice for Modern Replacement (DG511/Newer Models):
The ENA Set of 8 Straight Boot Ignition Coil Pack provides the ideal balance of affordability and proven quality for the common 2004-2008 F-150 platform. It’s a dependable, high-quality stock replacement.

Best All-in-One Tune-up Kit:
The MAS Set of 8 Ignition Coil DG508 & Motorcraft Spark Plug SP479 Combo is the clear winner if you need both parts. Using genuine Motorcraft spark plugs alongside quality coils ensures the entire ignition system is optimized from day one.

Best Ignition Coil For 5.4 Triton FAQ

What are the symptoms of a bad ignition coil in a 5.4L Triton engine?

The most common symptoms include engine misfires (often felt as a shudder or jerk, especially under acceleration), a rough engine idle, reduced engine power, and poor fuel economy. Typically, the Check Engine Light (CEL) will illuminate, and diagnostic codes (like P0301 through P0308, indicating a misfire in a specific cylinder) will confirm the ignition coil failure.

What is the difference between DG508 and DG511 coils?

The difference lies primarily in the application and physical design. DG508 coils typically feature a curved boot and were used mostly on 5.4L Tritons built before mid-2004. DG511 coils feature a straight boot (often black) and are used on models generally built from mid-2004 onwards. It is absolutely critical to check your original coil type before ordering any best ignition coil for 5.4 triton replacement set to ensure correct fitment.

Should I replace all 8 ignition coils at once, or just the failed one?

While you can technically replace only the failed coil to clear a specific misfire code, it is strongly recommended that you replace all 8 coils and spark plugs simultaneously. Ignition coils typically wear out at similar rates. Replacing only one often leads to another failure shortly after, forcing you to dismantle parts of the engine multiple times.

Are aftermarket ignition coils as good as Motorcraft coils for the 5.4L Triton?

Many reputable aftermarket brands reviewed here (like ENA and DRIVESTAR) meet or exceed the electrical specifications of the OEM Motorcraft parts. They are generally much more affordable. While Motorcraft offers guaranteed compatibility, if you choose a high-quality, high-review aftermarket set, you can achieve comparable longevity and performance at a fraction of the cost.

How long do the ignition coils typically last on a 5.4L Triton?

Original factory ignition coils often last between 80,000 and 120,000 miles. However, the 5.4L engine runs hot, which can shorten the lifespan of the coil-on-plug (COP) system. Aftermarket coils should provide a similar lifespan if high-quality materials are used, but they can be prematurely damaged if the spark plugs are heavily worn out.

What causes ignition coils to fail prematurely on the 5.4L engine?

The primary cause of failure is heat exposure inside the engine bay, leading to insulation breakdown and internal shorts. Worn-out spark plugs are another major culprit. If a spark plug gap becomes too wide, the coil has to work harder and increase its output voltage, stressing the coil’s internal components and leading to premature failure.
