taxfree4 - Yep that is the one. You'll also need 11524-MCA-010, which is the gasket for the front cover.

Willl's write-up is excellent, btw. He's right...getting to the plug is a pain if you're doing it all from the front, BUT if you're already doing the air filter, the plug is right there and easy to get to.

Some folks doing it as-needed (i.e. a roadside fix) have reported just cutting the wires and crimping or soldering versus using the factory plug.
