This listing is for an air cleaner assembly. It was removed from a Briggs and Stratton model #42A7071653-01 17hp opposed twin cylinder engine. It is in nice condition. It may fit other models as well. Please confirm that this part will fit your mower before purchase. Payment within 2 days of purchase. I will combine shipping on multiple purchases when possible. If you are looking for a part that I don't have listed please ask, I might have one. Thanks for looking!
