Ford Racing FRPP 3V Cold Spark Plug Set (12 mm Thread)

Ford Racing, known for its performance parts for Ford vehicles, offers these 3-valve cold spark plugs specifically for your Mustang. If you've got an engine that's running hotter or under more pressure than stock, these plugs are a solid choice. They are designed to handle those increased cylinder combustion pressures, helping to keep your engine running smoothly and reliably. This set is engineered with a unique design that's proprietary to Ford's 3-valve engines.

These spark plugs are one heat range colder than the OEM plugs found in the Mustang GT and two heat ranges colder than those in stock 5.4L truck engines. This colder heat range helps dissipate heat more effectively, which is crucial when dealing with higher combustion temperatures. This can help prevent pre-ignition and ensure consistent firing across all cylinders, keeping your engine performing at its best.

This set includes eight spark plugs, enough for a full engine set. They feature a 12 mm thread size, which is important to verify for your specific 3-valve heads.
