Stainless steel filtration is not a new technology but is quickly gaining popularity in the automotive segment. With the ability to filter down as small as a paper filter element with the ability to be washed and reused!

The K&P Engineering filter element is made from medical grade, type 304 stainless steel micronic filter cloth to provide unmatched protection against oil contamination and resultant engine damage. A one inch square of this material flows an incredible 1.9 gallons of oil per minute at only 1 PSI pump pressure. The adhesive used in the filter assembly process is good to 600 degrees Fahrenheit, far above normal engine operating temperatures. A super strength nickel-plated neodymium rare earth magnet is installed in the top of the element for magnetic pre-filtering of the oil. The sophisticated bypass is engineered for proper differential pressures and consistent operation, delivering a greater percentage of filtered oil while being very easy to clean. The twist lock design assures positive filter element placement and allows for easy disassembly, inspection, and cleaning. The quad-ring gasket doubles the seal between the filter and the engine. Finally, the filter housing is carved out of solid 6061T6 billet aluminum, which not only looks trick but aids in dissipating heat.

K&P Engineering manufactures stainless steel filters for a vast array of engines around the world. Staying at the forefront of design and testing allows this company to offer a top-tier product for your European vehicle.

Features:

  • Consistent filtering across entire filter surface
  • Superior ASTMF316 filtration performance
  • 7 times the flow of comparable paper oil filters
  • Magnetic Prefiltering
  • Progressive rate bypass combined with high flow characteristics of the filter media avoids unfiltered oil bypassing the filter during cold startup and high rpm
  • No more cutting apart messy paper filters for trapped debris inspection
  • Proven in Motorsports, Military and Aerospace applications for years. Technology is FAA approved for use in aircraft. 

At regular oil changes, clean to K&P's specifications for continued used - a true lifetime filter.

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:

E60 5 series : 525i 525xi 528i 528xi 530i 530xi 2004-2010

E85 Z4 : Z4 M Coupe Z4 M Roadster 2004-2008

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

Drop-in aFe high performance air that is made for the stock/factory BMW airbox on all the BMW twin-turbo engines, including the E60 535i & 535xi filter. This is designed to be the last air filter your BMW needs, as it is completely washable/reusable, and flows better than the stock paper air filters. On your BMW's twin turbo 3.0 liter engine, aspiration a BIG factor in producing power -- the better the airflow, the higher the potential power. Replacing your stock paper filter with an AFE high performance cloth/gauze filter takes only minutes and instantly reduces air restriction, for more horsepower and torque.



This item fits the following BMWs:
2004-2010 E60 BMW 525i 525xi 528i 528xi 530i 530xi 2006-2008 Z4 BMW Z4 M Coupe Z4 M Roadster This version used aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.
