Hi, This fits all engine sizes of 1998-1999 Mercedes Benz E320 sedan models without AMG styling package. To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page. We don't do painting on our body parts and only ship them primed. We suggest having it painted locally so they can correctly match the shade of your paint.

Hi Charisse, I'm glad to assist you. No. It is incompatible with the year 1991. It fits from 1998 to 1999 onwards Mercedes Benz E320 sedan, without a sport package (AMG styling package). You mentioned 1991 year. What model of Mercedes Benz are you referring to for 1991? There is no E320 on that year yet. I hope this helps.
