Filtration

Affinia Group is the world’s leading aftermarket supplier of oil, air, fuel, cabin air, transmission, hydraulic, and coolant filters for all types of vehicles and machinery - from NASCAR® race cars to earth-moving equipment, and from Mini Coopers to electricity-producing windmills. Well-known product brands, such as WIX Filters and Filtron, to private label brands, such as NAPA, assure market and brand leadership. Affinia Global Filtration follows a Prescription Filtration® approach, which means that filter media and design are specifically engineered for each application. This philosophy assures exact fit, form and function throughout all product lines.

Research and Development

Since 1954 and the first patented spin-on oil filter, WIX Filters has been at the forefront of filter technology and performance for passenger cars, light and heavy duty trucks and buses and off-highway vehicles. Across a product line that includes oil, air, cabin interior, fuel, coolant, transmission and hydraulic filters, Affinia adheres to strict Prescription Filtration design and construction on every filter. These designs and construction standards are backed by ongoing research and development and rigorous quality-control processes for the best possible filtration products for every application.

Heavy Duty

With a 70-year history in heavy duty filtration, Affinia Global Filtration manufactures and distributes heavy duty filtration products for diesel, agricultural, industrial, over-the-road and construction equipment. Heavy duty filters can stand up to whatever industry demands or brutal elements are thrown at them, providing optimal filtration and engine protection in less-than-optimal work environments.

Light Duty

There is nothing "light" about the Affinia light duty filtration product line. Years of research and development in filter media design and efficiency have resulted in the industry's most reliable and highest performing filters for passenger cars, light trucks and SUVs. Coverage of domestic and foreign nameplate applications is extensive with more than 4,400 different products.

Racing

For WIX Filters, an official NASCAR Performance Product, the racetrack is the most grueling testing ground imaginable for automotive and heavy duty filtration products.Thousands of miles of on-track research with NASCAR’s top teams translates into optimum performance on race day. The track provides an ideal testing ground for focusing on scenarios such as high temperatures, fluctuations in pressure and rapid breakdown of engine oil. Experience at the track has led to the development of filtration products incorporating leading edge materials and engineering.

Oil Filters

Oil is the life-blood of every vehicle, and oil filtration plays a vital role in protecting engines from premature wear and potential failures. From NASCAR tracks to construction sites and everywhere in between, Affinia oil filters are purposely "over-engineered" to handle a wide variety of fluctuations in flow and pressure, while withstanding vibration, high and low temperatures and constant spring-load pressure.

Air Filters

It takes only eight ounces of dirt to destroy a heavy duty engine. The typical off-road vehicle is exposed to 1½ to 2½ tons of airborne dirt each year, meaning first-rate air filtration is critical to the life of the engine. With a heritage in heavy duty filtration and a dedication to Prescription Filtration®, Affinia goes the extra mile with the design and construction of every air filter. Elements of our air filters, including patented silicone gaskets, oven-cured plastisol media stabilization beads and industry leading pleats-per-inch, assures that filters from Affinia contribute to superior performance and extended vehicle life.

Fuel Filters

Years of research and development in filter media design and efficiency have resulted in the industry's most reliable and highest performing fuel filters for passenger cars, light and heavy duty trucks and buses and off-highway vehicles. Fuel filters are essential in helping to protect fuel system components from contaminants that may be in the fuel. These contaminants can plug fuel injectors or carburetors, causing engine malfunction and deterioration. Dirt, rust, scale and water are the major impurities present in fuel. These impurities can originate from dirty and rusty service station storage tanks and, as the vehicle ages, from corrosion within the fuel system components.

Cabin Air Filters

Cabin Air Filters not only protect a vehicle’s HVAC system, they also protect the vehicle’s occupants from soot, dirt, pollen and other pollutants. At Affinia, we have taken additional steps to protect the air our customers breathe by adding BioShield 75 to most of the cabin air filters we manufacture. BioShield® 75 traps and eliminates harmful microbes in the filter medium and reduces the opportunity for those microbes to be released into the air breathed by vehicle occupants. Today, more than 80 percent of all new foreign nameplate and domestic vehicles sold in the U.S. have a cabin air filter or a slot where one can be installed, making cabin air filtration the fastest growing segment in the filter market.

Coolant System Filtration

Fifty-three percent of all catastrophic, premature diesel engine failures are directly related to improper cooling system maintenance techniques and habits. Using the correct water, antifreeze and supplemental coolant additives in cooling systems is more critical than ever to insure trouble-free service life. Affinia has kept pace with the changes that directly affect coolant-filtration products and cooling system additives. Affinia also offers several services to help properly test and service heavy duty cooling systems. From a chemical-additive and coolant-filtration perspective, Affinia offers everything heavy duty operators need to maintain heavy duty cooling systems.

Hydraulic Filters

Affinia Global Filtration applies its superior filter design and manufacturing expertise to produce high quality hydraulic filters for over-the-road, agricultural and construction vehicles and equipment. Sophisticated equipment depends on clean hydraulic fluids to operate critical functions at peak efficiency, meaning fluid contaminants must be kept to an absolute minimum. This challenge can be serious given the rugged and dusty environments these vehicles and equipment work in every day. Hydraulic filters from Affinia are designed to withstand even the most rigorous operating conditions.
