Genuine Motorcraft SP548X CYFS12F1 Platinum Spark Plug for Cadillac, Ford, GMC

The Motorcraft SP548X CYFS12F1 Platinum Spark Plug is an OEM (Original Equipment Manufacturer) spark plug primarily designed for Ford vehicles. Motorcraft is Ford’s in-house brand, ensuring that the parts meet factory specifications for Ford, Lincoln, and Mercury vehicles. However, these plugs may also fit certain Cadillac and GMC models, but it's crucial to check vehicle compatibility before purchasing.

Here are a few key features of the Motorcraft SP548X CYFS12F1 spark plug:

• Platinum Tip: Platinum enhances the lifespan of the spark plug, offering better wear resistance than standard copper plugs. This results in a longer service life and fewer replacements.
• OEM Quality: Designed specifically for Ford models, it ensures the proper fit and performance, supporting engine efficiency and reducing misfires.
• Heat Management: Provides optimal heat range and corrosion resistance, helping to prevent fouling and ensuring consistent engine performance.

Before using it in a Cadillac or GMC vehicle, verify whether it is the correct fit for your model by consulting the vehicle’s manual or using a reliable parts compatibility tool. Generally, these plugs are tailored more to Ford applications than GM brands.
