Check Vehicle Fit

Have you noticed the small filter located in the air filter housing? Have you ever wondered what it’s for? Or have you possibly thrown it away? That small filter is known as a breather. Breathers, also known as emission control filters, filter fresh air that’s drawn into the engine’s crankcase. Because the engine must breathe to purge itself of fuel and water vapors, breathers are used in conjunction with the PCV valve. Although small in size, Purolator breathers are big in importance. Like any other filter, the breather is used to trap harmful contaminants and prevent them from damaging the engine. Failure to change the breather will allow unfiltered air (with all of its contaminants and dirt) to be drawn into the engine crankcase which can cause engine damage. Generally, the breather element should be changed every 12,000 miles - however, check with your vehicle manufacturer's recommended change interval as it may vary. The simplest recommended plan of preventive maintenance is to change the breather element at the same time the air filter is changed. This eliminates trying to juggle and anticipate two different change intervals, and it's convenient because you'll be able to access two filters in the air filter housing at once. Not all vehicles are equipped with a breather element. Use the Purolator Application Guide or contact the Pros to find out if your vehicle has a breather. If it does, visit your favorite automobile parts retailer and ask for a Purolator breather filter today!
