[SVXdc]

One of my knock sensors just went bad (getting a CEL), so I'm now shopping for them.

The newer 22060AA031 does indeed supercede the older part.

According to the parts search at SubaruGenuineParts.com, this same part number is also used in:

• Impreza 1995-1996
• Legacy 1990-1996
• SVX 1992-1997

Current prices (8/2007):
