1995 C4 tune up

[boomerang]

I have a 1995 C4 Coupe with 123K miles and have (from the symptoms I have read about in this forum) a bad O2 sensor. I am going to replace them as well as the spark plugs and wires. Any suggestions on brands of plugs, wires, O2 sensors...NGK, Bosch, Champion, etc?

AC Delco all the way for me. No reason to change.

Plug wires are an "experience" (to say the least) to change (driver's side that is). :W

O2 sensor going bad symptoms....rich running with black smoke coming from one side of engine exhaust, rough idling. These symptoms started for me after running fine, shuttting it off and then restarting. I get the check engine light intermittantly and does not stay on to check for a code. I read posts on this forum that mimic my problem and they too say an O2 sensor.
