I am new to these cars and will do some more research before I tackle the project, thanks for the heads up. AC Delco looks just like the 50 dollar filter others sell so I went ahead and bought one of each, just to be safe. I dont think Rock Auto would have it listed as correct if it did not do the job of the stock filter but you never know. Just to be safe I bought another one for 7.28 ! It make no difference to me if the box is damaged when i am only using the filter.
