At Harold's Used Auto Parts Inc in Philadelphia, we see a lot of dirty filters. Oil filters typically get replaced with each oil change, but air, fuel, and cabin filters last a long time. As such, they are often neglected until well after they’ve run their course. Here’s why you should care:

Filters are your first line of defense. Air, fuel, and oil entering your engine go through the filter first. If the filter is highly contaminated, elements entering your engine will be, too. Cabin filters keep pollen and dust out of your car when the A/C is running, keeping debris out of your vehicle and out of the HVAC system inside your cabin.

More importantly, a clogged filter is a hindrance to whatever is trying to flow through it. Clogged oil filters decrease oil pressure, potentially ruining an engine. Clogged air filters overwork your engine and decrease performance. Dirty cabin filters wear out your cabin fan, and prevent air from circulating inside your car, to the point the A/C may stop cooling altogether. Expired fuel filters cause the fuel pump to work extra hard, causing it to overheat or fail more quickly, and cause a pressure reduction which prevents injectors from properly functioning.

Filters are inexpensive and quick fixes, and will save you thousands in prevented malfunctions. Not to mention, you’ll experience a substantial increase in gas mileage and performance from replacing a soiled filter. If you need your filters replaced, or any other repair or maintenance performed on your car, truck, or SUV, our expert mechanics are here to help. Call or visit Harold's Used Auto Parts Inc today.
