      Lower Chances of Engine Misfires. Installing these 1 Range Colder Copper HP Spark Plugs help you lower your truck’s chances of having engine misfires. Compared to iridium or platinum plugs, these copper plugs offer better conduction, allowing them to deliver stronger spark energy. What’s more, these spark plugs feature a C-cut design, enabling them to create a more efficient burn.

      Copper Construction. These HP Spark Plugs are made with a copper core. This material allows for better conduction as well as heat dissipation. With the plugs cooling at a faster rate, your truck’s ignition system will be able to deliver consistent performance. Furthermore, these copper spark plugs are built to be gapable, so that you can open or close the gap depending on your driving needs.

      Direct Installation. Each of the spark plugs can be directly installed to your truck’s factory location points using simple garage tools. If you are equipped with light to moderate mechanical skills, you can quickly finish the installation. If you encounter any problems during the installation, it is recommended that you seek the help of a professional mechanic.

      Covered by a Limited 90-Day Warranty. These products are covered by ACCEL’s limited 90-day warranty. However, this warranty excludes any damages that are due to abuse, accident, alteration, modification, improper installation, improper operational adjustments, tampering, negligence, misuse, and unauthorized repairs. For more warranty information, you may visit the official manufacturer website.

      Application. These 1 Range Colder Copper HP Spark Plugs are engineered to fit 2011-2022 3.5L EcoBoost Ford F-150 models.
