Good To Know

Q: Do I need to replace this gasket every time I remove the throttle body? A: Yes, gaskets are single-use sealing components and should be replaced whenever the throttle body is removed to ensure a proper seal.

Q: Can I reuse the old gasket if it looks intact? A: Reusing a compressed gasket risks vacuum leaks, so a fresh replacement is recommended for reliable sealing.

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