aFe Magnum FLOW lifetime, oiled, replacement air filter. This is last air filter you will ever need to buy. When it gets dirty, rather than throw it away like a paper filter, you renew it by using aFe's filter cleaner and filter oil. Renewable cotton air filters are nothing new, but this aFe replacement filter is different than the others on the market. It features:
- Multiple layers of oiled, cotton gauze sandwiched between two layers of epoxy-coated aluminum screen and pleated like a lampshade. The layers of gauze are stacked to catch progressively smaller and smaller particles, down to 2 microns in size.
- The deepest pleats in the industry, with rounded tips instead of pointed folds. Deeper, rounded pleats means more filter material to hold more dirt. Plus the pleats can be spaced further apart, allowing more air to enter your engine.- 100% polyurethane frame that withstands extreme engine temperatures and extends service life (i.e. no plastomers to dry out and crack). In fact, all aFe replacement filters come with a limited Lifetime Warranty.
- A pliable, progressive, polyurethane bump seal that provides a tight seal in your car's factory air box without the use of gaskets or messy sealants. (It seals even if the air box has an uneven sealing surface.)Customers who have installed aFe lifetime air filters tell us that with the increased air flow, they notice improvements in both performance and fuel economy. Specific gains will depend on the age and condition of your vehicle. Even if the performance gain is minimal, over time you will save money by not buying a new filter every 15,000 miles. Plus you'll help the environment by not using a disposable filter. Note: To clean and re-oil this filter, you will need to buy an aFe filter restore kit (#90-50501).
