New AMSOIL Bypass Oil Filters For Ford PowerStroke And GM Duramax

Bypass oil filtration has come a long way since the days of toilet paper being used as a filter element. As with any bypass oil filter system, a small portion of the engine oil is slowly run through a very fine filter element. Except in that case, ordinary single-ply toilet paper was used. We aren’t kidding. There are still systems on the market today that use toilet paper to filter engine oil.

AMSOIL’s bypass oil filter systems have never been suitable for bathroom duty. They use a very sophisticated filter media which leads the market with exceptional filtration efficiency, dirt-holding capacity and durability. Now AMSOIL has released two new systems that make for easy installation on Chevy/GMC Duramax diesel engines and Ford PowerStroke (6.0L and 6.4L) diesels. These oil filters systems remove soot and dirt down to less than 2 microns for extended oil life and reduced engine wear.

Oil Bypass Filter System For Ford 6.4L/6.0L PowerStroke Diesel Engines

The new BMK-31 for modern Ford PowerStroke diesel engines is a single remote bypass filter. This means that a single bypass filter is employed, while the factory full-flow oil filter stays in place. The BMK-31 kit comes with all of the parts, filter base and spin-on bypass filter, hoses and fittings needed for easy installation. An ingenious billet aluminum full-flow oil filter cup replaces the stock unit (note the right-hand item in photo). A fitting on the end of this location draws a small portion of engine oil out of the full-flow oil filter housing and runs it through the bypass oil filter. The ultra-clean oil is then returned to the engine through a custom billet oil filler cap. The fit, finish and construction of all of the components of this kit are truly top shelf.

New Oil Bypass Filter System For GMC/Chevy 6.6L Duramax Diesel Engines

Like the Ford system, the BMK-32 system for GM Duramax diesel engines is an easily installed single by-pass filter system. In order to draw oil from the engine, AMSOIL uses a clever billet aluminum “sandwich adapter” that fits between the engine’s spin-on full-flow oil filter and the filter base (note the right-hand item in photo). Oil is drawn through a fitting on this sandwich adapter, passed through the oil bypass filter and then returned into the engine through a billet aluminum oil filler cap (that has a return fitting on top). The filter base, bypass filter element, hoses, fitting and parts are all included in this kit.
