Get a 45 degree filter adapter and use the longest one that will fit. More filtration area always a good thing. WIX are good. Just change them regularly. Go by the time, not necessarily the mileage unless it is your daily driver. It is the acids and contaminates that do the most harm to the internals and seals. And cars that are not driven regularly (just started up every month) are the worst as they build unburned fuel, moisture from not being driven long enough to bring up the engine and all the fluids to proper operating temperatures which will evaporate a lot of the moistures and allow the fluids to do their jobs. . Look at the tail pipe a few minutes after you start the car in the morning. Wonder what all the moisture came from ?
