I have a 1994 E320 that just failed the emissions inspection.

I plan to replace the Catalytic converter and the O2 sensor.

I've seen some Universal catalytics but I'm not sure if I should go for it.....or I should stick only to the original from mercedes.

I would appreciate any comments.

For starters...MOVE!! ok, just kidding. I had always ran my tanks real low and put a couple bottles of heet in the tanks and never had a problem passing emmisions. I would do something like that before spending all that dough on stuff you may not need. Are you in a blue state too?? (democratic)?

To start I'd run a few liters of water through your engine, change the oil and pull the air filter.
Next, drive your car at High RPM for a few days, ie leave it in 3rd when cruising..

Also, when was your O2 sensor changed last? Plugs/wires/leads?
What part of your emissions did you fail exactly?

Need parts? Give a call, I don't sell anything I wouldn't install on my own car.
