Comparison Insights: Choosing the Right Metal

When selecting the best spark plugs for your 2013 F150 5.0, the material is the biggest factor affecting performance and how often you’ll need a spark plug replacement.

The OEM Standard vs. Performance Materials:
The benchmark is the Motorcraft SP548. It’s engineered specifically for your 5.0L V8 and is your safest bet for avoiding issues. If you want maximum reliability and don’t mind changing them at the manufacturer-recommended interval (usually 60,000 to 100,000 miles, depending on driving), stick with OEM.

Iridium vs. Platinum:
Iridium plugs (like those from NGK Iridium IX or the various A-Premium iridium options) are the current industry standard for longevity. Iridium has a higher melting point than Platinum, allowing for a finer wire tip that requires less voltage to fire. This translates to a stronger, more focused spark and the longest service intervals (up to 100,000 miles). Platinum is a great step up from standard materials but generally offers slightly less longevity than top-tier Iridium.

The Coil and Plug Combo:
If your truck has over 100,000 miles and you’ve never changed the ignition coils, considering a kit like the A-Premium Ignition Coils and Spark Plugs Kits is highly recommended. Often, what drivers perceive as a bad spark plug is actually a weak coil failing to deliver enough voltage, especially under load. Replacing both simultaneously ensures optimal performance.

The Bottom Line: Best Spark Plugs For 2013 F150 5.0

Choosing the right plug depends on your maintenance philosophy and budget. Here’s a quick breakdown of our favorites:

If You Prioritize Guaranteed Reliability (The Safe Bet):
The New Motorcraft SP548 Spark Plug Set of 8 is the undisputed champion here. It’s what Ford built the truck to run on, eliminating any uncertainty about compatibility or heat range.

If You Want Maximum Performance and Longevity (The Upgrade):
The 8 pc NGK Iridium IX Spark Plugs offer superior performance, outstanding durability, and a reputation you can trust. They provide the sharpest, most consistent spark over the longest duration, which is crucial for maximizing efficiency in the Coyote engine.

If You Need a Full Ignition System Refresh (Best Value Kit):
For high-mileage trucks, the A-Premium Ignition Coils and Spark Plugs Kits provides the best all-around value. Getting new iridium plugs and coils in one package means you are completely refreshing the ignition system, addressing any potential coil fatigue that might be causing misfires.

Comprehensive FAQ: Best Spark Plugs For 2013 F150 5.0 V8

Do I really need iridium spark plugs for my 2013 F150 5.0 Coyote engine?

While your truck came from the factory with platinum plugs (the OEM Motorcraft SP548), upgrading to iridium (like NGK or certain A-Premium plugs) is highly recommended. Iridium offers superior heat resistance, requires less voltage to fire, and provides the longest service life, often pushing replacement intervals up to 100,000 miles.

What is the correct spark plug gap for the 2013 F150 5.0L V8?

The correct gap for the 5.0L V8 can vary slightly, but generally, factory specification calls for a gap around 0.049 to 0.053 inches. Some performance plugs, especially those designed for high boost, may run slightly tighter. Always confirm the specific gap with the plug manufacturer or your owner’s manual, and gently re-gap the new plugs if necessary before installation.

How often should I replace the spark plugs in my 5.0L F150?

For OEM Motorcraft or high-quality platinum plugs, the recommended interval is typically between 60,000 and 80,000 miles. If you choose premium iridium spark plugs, such as the NGK Iridium IX or long-life A-Premium options, you can often safely extend this interval to 100,000 miles under normal driving conditions.

Should I replace my ignition coils at the same time as my spark plugs?

It’s highly recommended, especially if your truck has reached or exceeded 100,000 miles and you are experiencing misfires. Ignition coils degrade over time due to heat and wear. If you only install new spark plugs (like the SP548 replacement) but retain old, weak coils, you won’t get the full benefit of the new plugs and may experience continued issues. Coil/plug kits like those from A-Premium offer an easy solution for a full Coyote tune-up.

Are aftermarket ignition coils reliable compared to Motorcraft?

Aftermarket coils, such as those included in the value kits, can offer a good cost-saving alternative. However, genuine Motorcraft parts are generally considered the gold standard for longevity and exact fitment. If you prioritize budget and are comfortable with the chance of a shorter lifespan, aftermarket kits are a great choice. If you prioritize absolute peace of mind, stick with OEM coils.

What are the signs that my 2013 F150 5.0 needs a spark plug replacement?

Look out for symptoms like a decrease in fuel economy (MPG), a noticeable loss of power or hesitation during acceleration, engine misfires (often felt as a shudder, especially under load), and a rough or unstable idle. These are classic indicators that your spark plugs for 2013 F150 5.0 are worn out or fouled.
