2001 150 5.4 pulled out a agsf 22w book says awsf 22w are they the same?

 

The "A" plug numbers have been replaced with "SP" numbers. The correct plug is SP-479. This replaces the AGSF22. The AG's are full thread, the AW's are 1/2 thread. The full thread is now specified for use in both the half thread and full thread heads. The half thread can NOT be used in the full thread (2003+) heads.

 

Ok thanks is the gap the same?

 

Yep, and it should be pregapped correctly. Wouldn't hurt to check though.
