Good To Know

Q: Does this throttle body need a relearn after install? A: Most vehicles require a throttle position relearn with a scan tool so the ECU recognizes the new unit and idles correctly.

Q: Can I install this without removing the intake manifold? A: Yes, on the 4.6L V8 the throttle body mounts to the front of the intake and is accessible without pulling the manifold.

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