WIX Filters

Since 1939, WIX® Filters has been an innovator in filtration products. WIX designs, manufactures and distributes products for automotive, diesel, agricultural, industrial and specialty filter markets. Part of the MANN+HUMMEL family of brands, the WIX Filters product line includes oil, air, cabin interior, fuel, coolant, transmission, and hydraulic filters for automobiles, trucks, off-road equipment, and manufacturing applications.
This is the oil filter of choice for severe drivers who use conventional, synthetic or synthetic-blended motor oil. Their drives are usually stop-and-go, either in the city or in heavy traffic. They may also drive in dirty or dusty conditions. They usually change their oil every 3,750 or 10,000 miles, not to exceed 12 months.
Engineered to withstand the toughest of driving conditions and scientifically designed to maximize the performance of synthetic motor oils, our XP oil filters provide optimum protection for the increased demands on today’s vehicles. Heavy loads, towing, high-idling city and harsh driving conditions are no match for the enhanced durability of XP. You change your oil at suggested OE manufacturer oil intervals with synthetic oil, typically every 3,750 to 10,000 miles, not to exceed 12 months.
Keep yourself happy with our premium WIX cabin air filters, which are exclusively enhanced with Microban odor and antimicrobial technology. They reduce contaminants your passengers breathe and help keep the interior of the vehicle clean. They should be replaced every 12 months or 15,000 miles.

When To Change Your Air Filter

What’s the purpose of an air filter? An air filter prevents dirt, leaves, insects and contaminants from entering your engine. Common signs that it is time to change your air filter are a decrease in gas mileage, rough idle or engine misses, the ‘check engine’ light comes on, decreased acceleration and the smell of gasoline when starting your car.
