WIX Filters Oil Filters
WIX oil filters play a vital role in in your vehicle's lubrication system, protecting your engine from premature wear. As gearheads know, every moving part in the engine requires clean oil! WIX oil filters trap more dirt than the leading national brand, and they keep filtering long after the competition has completely quit. WIX patented the first spin-on oil filter in 1954 and has been at the forefront of filter technology ever since. Canister-style oil filters feature strong, full-metal base plates to prevent leaks at the double seam under severe driving conditions. They also offer glass-enhanced media that improve each filter's ability to catch and hold engine-damaging dirt. Choose the WIX oil filter to fit your make and model—for a cleaner-running engine over many extra miles.
