Installation Notes

Before installation, verify the connector shape, terminal count, and mounting style against the original part. Because this is a complete assembly, inspect the intake tract and connector air tubes for dirt or residue before installing the new unit. Avoid touching the sensing element with bare hands and confirm the vehicle application matches the listed year, make, model, and emissions configuration.
