Oil Filter

These are the most often replaced items on a car, so get familiar with them. As the name implies, they simply filter the engine's oil, and being as oil is the lifeblood of any engine, their job is crucial. Oil filters should be replaced with every single oil change--and you should strongly consider OEM-specific oil filters as well. It is a good idea to buy these in bulk if you change your own oil--with crush washers, of course.
