Good To Know

Q: Do I need to replace this gasket after removing the throttle body? A: Yes, this style of gasket is commonly single use, so a fresh one helps prevent leaks once the throttle body is reinstalled.

Q: Should I torque the throttle body fasteners to spec? A: Yes, follow the factory torque values for your 1503 HO engine to avoid crushing the gasket or distorting the housing.

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