Do Honda and acura interchange parts?

In some cases, yes. Honda and Acura are both owned by the same parent company, Honda Motor Company, and some parts are interchangeable between the two brands. However, it is not always the case that parts from a Honda will fit an Acura, or vice versa. It is important to check with a qualified mechanic or parts dealer to ensure that the parts you are looking for are compatible before you purchase them.
