    Spark Plug – Ford (ASF-42C-X)

    The Spark Plug – Ford (ASF-42C-X) is a Genuine OEM ignition component engineered to deliver consistent spark performance and dependable combustion in Ford engines designed for this specific specification. Manufactured by Ford, this spark plug is produced to strict factory standards to ensure accurate ignition timing, smooth engine operation, and long-term reliability.

    Constructed using high-quality metal alloys with a precision-engineered electrode design, this spark plug is built to withstand high combustion temperatures and continuous electrical load. The calibrated heat range helps maintain optimal combustion chamber conditions, supporting efficient fuel ignition while reducing the risk of fouling, misfires, or pre-ignition throughout the service life of the plug.

    This spark plug is vehicle-specific and intended for Ford applications requiring part number ASF-42C-X. OEM fitment ensures correct thread size, reach, and sealing characteristics, allowing for direct installation without modification. Professional mechanics benefit from predictable ignition performance and reduced diagnostic issues, while DIY mechanics can confidently perform replacement using standard tools and manufacturer-recommended torque specifications.

    Functionally, spark plugs play a critical role in engine efficiency, drivability, and emissions control. Worn or incorrect spark plugs can lead to rough idle, hesitation, reduced fuel economy, and increased emissions. Replacing them with a Genuine Ford OEM spark plug helps restore proper combustion and supports long-term engine health.
