Good To Know

Q: Can I reuse the old gasket? A: No, gaskets are designed for single use and should be replaced each time the throttle body is removed to prevent vacuum leaks.

Q: Does this include mounting bolts? A: This listing covers the gasket only, so reuse or source mounting hardware separately if needed.

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