Comparison Short Insights for 2013 F150 Ecoboost Plugs

When choosing ignition components for your 2013 F150 Ecoboost, the decision usually comes down to OEM loyalty versus value-added combos.

If you prioritize absolute peace of mind and factory compatibility, the standalone Motorcraft SP580X or the OverstockDirect OEM Iridium pack are your top choices. They offer the exact heat range and design Ford engineers specify for optimal performance.

For those seeking the best performance and tuning stability, the NGK Iridium IX plugs are often favored by the enthusiast community for their consistency under high boost. The Champion Iridium plugs are also a fantastic performance alternative focusing on superior flame kernel design.

The best value proposition is consistently found in the combo kits. The MCK set is particularly noteworthy because it wisely pairs OEM Motorcraft spark plugs with aftermarket coils, offering a substantial cost saving while retaining the most critical component (the plug) from the factory supplier. Other combo kits like Yoshi Motors and AULINK provide great bang for your buck but require trust in their third-party plugs and coils.

Always remember to check the gap. The single most important factor for an Ecoboost is having the correct gap, typically tight (0.028” to 0.030”), regardless of whether you choose OEM or aftermarket Iridium plugs.

Final Verdict

Choosing the right spark plug for your 2013 F150 Ecoboost depends heavily on your budget and how you use your truck.

For the OEM Purist (Best Overall Reliability):
The OverstockDirect OEM Iridium Spark Plugs (6 pack) SP580X provide guaranteed factory performance. If your coils are under 50,000 miles, replacing the plugs with OEM ensures your truck runs exactly as Ford intended.

For the Best Value (Coils + Plugs):
The MCK 6pcs Ignition Coil Pack And Motorcraft Iridium Spark Plug is the smartest budget choice. By combining reliable, genuine Motorcraft plugs with cost-effective coils, you get OEM performance where it matters most while simultaneously addressing potential coil wear.

For the Performance Enthusiast (Best Ignition Stability):
Opt for the 6 pc NGK Iridium IX Spark Plugs. These are engineered to withstand rigorous conditions and offer the stability needed if you plan on running performance tunes that increase boost pressure.

Best Spark Plugs For 2013 F150 Ecoboost: Frequently Asked Questions

Q1: What is the correct spark plug gap for a 2013 F150 Ecoboost?

A: The factory gap is often around 0.030” to 0.032”. However, because the 3.5L V6 is turbocharged, most experienced owners and tuners recommend tightening the gap slightly to 0.028” or 0.029”. A tighter gap helps prevent spark blowout under high boost, leading to fewer misfires and smoother acceleration. Always verify the gap before installation, even if the plugs are “pre-gapped.”

Q2: How often should I replace the spark plugs in my Ecoboost engine?

A: Ford generally recommends replacing Ecoboost spark plugs around every 60,000 to 70,000 miles under normal driving conditions. If your truck is tuned, runs higher boost, or is frequently used for towing, it’s highly advisable to shorten this interval to every 30,000 to 40,000 miles to maintain optimal performance and prevent misfires.

Q3: Should I replace my ignition coils at the same time as the spark plugs?

A: For the 2013 F150 Ecoboost, replacing the ignition coils simultaneously with the spark plugs is often a wise preventative measure, especially if the truck has over 80,000 miles. High heat and pressure can degrade the coil packs over time, causing intermittent misfires that new spark plugs alone cannot fix. Combo kits like the Yoshi Motors or AULINK sets offer a comprehensive solution.

Q4: Are Iridium spark plugs necessary for this turbocharged engine?

A: Yes, Iridium plugs are highly recommended and essentially standard for the Ecoboost. They offer far superior durability and a much longer life than copper or platinum plugs. The Iridium material resists the high-temperature demands and erosive effects of direct injection and forced induction better than any other standard spark plug material.

Q5: Can using the wrong spark plug heat range cause problems?

A: Absolutely. Using a plug with an incorrect heat range (too hot or too cold) can cause significant engine issues. A plug that runs too hot can lead to pre-ignition and catastrophic engine damage, while a plug that runs too cold can cause fouling and persistent misfires. Motorcraft SP580X and equivalent Iridium plugs are engineered with the correct heat range for this application.

Q6: What are the symptoms of failing Ecoboost spark plugs or ignition coils?

A: Common symptoms of worn out Ecoboost spark plugs or failing ignition coils include noticeable engine misfires (especially under heavy acceleration), poor or surging idle, decreased fuel economy, difficulty starting, and the illumination of the check engine light (DTC codes related to P0300 misfires).
