The 5.0L Mustang spans multiple generations, from the classic 302 Windsor to the modern Coyote V8. Choosing the right spark plug requires matching your engine’s specifications. Modern 5.0L engines benefit from iridium or platinum electrodes for longevity and stable ignition, while classic Windsor-based 5.0L engines are better suited to traditional copper plug designs .
For the 2011-2017 Coyote engine, the Motorcraft SP548 plug serves as a reliable OEM-grade option, ensuring consistent ignition performance . For the classic Fox Body Mustang (1987-1995), the Motorcraft ASF42C copper spark plug kit offers a direct factory replacement for stock engines, featuring a copper core with a nickel alloy tip .
If you are modifying your Mustang for performance, a colder heat range plug can be necessary to reduce the chance of pre-ignition and detonation

Complete Buying Guide for Spark Plugs For 5.0 Mustang
Essential Factors We Consider
When picking out the right spark plugs, we look at the material composition (Iridium vs. Copper vs. Platinum), the heat range, and the specific needs of the engine year. Modern Coyote engines have much tighter tolerances and higher heat profiles than the classic Windsor engines, so choosing a material that can handle that temperature is vital.
Budget Planning
You don’t need to overspend to get great performance. For most owners, a reliable V-Power plug is perfectly fine. If you want to reduce the frequency of maintenance, however, upgrading to Iridium is well worth the extra upfront investment.
Final Thoughts
Your 5.0 Mustang is a machine that thrives on a good spark. Whether you choose the performance-oriented Iridium options or the classic V-Power style, keeping your plugs fresh is the best way to ensure your car stays on the road where it belongs.
