You need to look at the parts list and determine the part numbers needed for your engine then compare it to the tune-up kits available. 5138WEB would be the tune up kit.

It says Foam - OR- Paper filter. Does that mean it has both and you can choose which one to use? Or that it will show up with whatever happened to be put in the box at the time of packaging?
