OE Replacement for Stock and Tuned EcoBoosts
Ford puts a lot of effort into the spark plugs that go into their latest generation of F150 engines, and their Motorcraft Iridium Spark Plugs are a surprisingly good choice for the 2011 to 2016 F150s rocking a powerful 3.5L EcoBoost V6. These spark plugs generate a clean, intense burn and come standard with an iridium tip that's highly resistant to fouling, corrosion, and general wear. These plugs are highly adaptable and can be used on bone-stock trucks and even aggressively tuned and heavily modified EcoBoost F150s when gapped down. These plugs come highly recommended by 5-Star Tuning for all of their performance tunes and are a great way to get your EcoBoost F150 back in tip-top running condition.
Can be Gapped Tighter for Tuned Trucks
This full set of six spark plugs come stock in newer 2013 to 2014 F150 EcoBoost trucks and provide excellent performance improvements for the 2011 to 2012 EcoBoosts thanks to their revised design, iridium tips, and slightly tighter gap. The plugs are simple, easy replacements for your truck's factory plugs and are an excellent way to squeeze improved performance out of your truck. For tuned vehicles, 5-Star recommends gapping each plug down to .030" for best performance.
Gapping for Stock Trucks: while a smaller gap is not required for bone-stock EcoBoosts, it's extremely important to make sure gapping is consistent across all six plugs before installation.
Plugs will need to be gapped and/or have their gaps checked before final installation.
