Before you buy

Emissions rules differ by state, and some states require a specific type. Fix the cause of the failure, such as misfires or burning oil, or the new one can fail too.

Confirm the part fits your exact 2003 Ford Focus by checking your VIN, engine size and trim with the seller. The Focus was sold with different options across the 2003 model year, and a part that fits one build may not fit another.
