The oil filter in your vehicle is one of the most important maintenance components it has. It's important that you are changing your oil on a regular basis and also swapping out the filter so that your car is running on the highest quality oil possible. There are a range of different components associated with the process as well. The oil filter housing is what helps to secure your filter in place. The filter housing plays an important role in keeping the clean oil circulating to your engine. Your filter gets put into the housing and your oil filter cap is what helps to secure the housing in place. If your oil filter cap and housing gets worn out, the engine oil isn't able to flow through your filter the way it should. When you need replacement filler caps and housing, be sure to invest in OEM parts. Only OEM oil filter caps are going to fit with the rest of your system perfectly.
