Hi Paul, I'm pleased to assist you. This item isn't the right side skirt for the 2011 BMW 328i. We suggest that you get the side skirt for your car from the local auto parts store.

Hi Eugene, Unfortunately, we do not list a second option for that part based on the vehicle application you selected. This one says on the fitment "with models for M Sport Line..". Probably you need the one without M Sport Line. To check the fitment accurately again please use our Vehicle Selector — which can be found towards the top of the homepage as well as all category, 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.
