Model, trim and equipment availability can vary. Compare the original component, mounting location and product photographs before ordering.
- Support the vehicle securely and inspect the lower front mounting structure.
- Remove damaged remnants and clean the attachment points.
- Orient the tall air dam so its airflow surface faces correctly.
- Test-fit the complete one-piece molding before tightening any location.
- Secure the part evenly without drawing it into a twist.
- Verify ground clearance and monitor operating temperature after service.
Is this the short Formula air dam?
No. This is the taller Trans Am/GTA ground-effects design.
Why is the air dam important at highway speed?
It helps build pressure ahead of the radiator opening and directs air through the cooling stack.
What material is the reproduction?
Hawks identifies durable ABS plastic similar to the original application.
Will a lowered car need extra care?
Yes. Restored full height reduces ground clearance compared with a worn or bent original.
What part number does it replace?
The air dam references GM 10017672.
