Worked well on a 2003 4 cylinder Legacy. The bottom screw on the back is a little tricky to get to, so I recommend a low profile ratchet like the Tekton SRH01006 along with a 10mm socket with a 1/4" drive, the shorter the more better. One of the screw heads was badly rusted, but I was able to grab it with a 3/8" socket. Do not overtighten the screws! They have a shoulder, so don't try to get past where they hit the ground.
