There is only one spark plug you should ever use on the UrS4/6.  It is the
Bosch F5DP0R.  It is a single electrode, not four.  They're not cheap plugs.
Best price seems to be around $12 each, but they last 60k miles.  Several
have tried different plugs in an attempt to find a less expensive solution,
and as I recall they have all gone back to the F5DP0R after misfires develop
with the other plugs.
