Good To Know

Q: Will this sensor clear my check engine light? A: A MAF-related code may clear once the faulty sensor is replaced, but other faults can trigger similar codes. Scan for stored codes before ordering.

Q: Should I confirm the reference number first? A: Yes, match the 5WK9641 reference against your original sensor or vehicle listing. Engine variants can use different airflow meters.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
