Adding more boost on your ST Focus? These Spark Plugs (M-12405-20T) from Ford Racing are two heat ranges colder than stock, which is ideal for higher-boost applications.
Features and Benefits:
- Two heat ranges colder
- Genuine Ford Racing parts
- Great for additional boost
- Pre-gapped to 0.028-inch
Colder spark plugs are designed to only ignite fuel when they're supposed to. These spark plugs won't stay hot while not firing, unlike a "hotter" plug. This is ideal when more air and fuel are forced into the combustion chamber, by a turbo or supercharger. Running a hotter plug with boost can result in detonation - or, premature ignition of your fuel. Prevent that from happening with these colder plugs!
Tech Tip: The spark plugs in this set are two heat ranges colder than the stock EcoBoost engine spark plugs. They are the same spark plugs that are included with the Ford Racing Calibration Kit (M-9603A-FST).
Please Note:
- Sold as a set of four spark plugs. They come pre-gapped to 0.028-inch (0.71mm).
- Using spark plugs with too hot of a heat range may result in detonation. If too cool of a heat range is used, the spark plugs may foul.
