Specs At A Glance

Good To Know

Q: How do I know if my throttle body gasket needs replacing? A: Common signs include a rough or wandering idle, whistling from the intake area, and lean-running codes. A flattened or torn gasket at the throttle body flange is often the cause.

Q: Should I torque the throttle body bolts after fitting this gasket? A: Yes, tighten the mounting bolts evenly in a cross pattern to the specification for your 1503 260 engine. Even torque helps the gasket seat properly and prevents future air leaks.

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