Engine wear is caused by dirt particles larger than 5 microns. The AMSOIL Bypass Oil Filter is 100% efficient at 2 microns now, virtually eliminating engine wear. Other advantages include protection against acid causing soot, carbon, varnish, and other oxidation components.
Upgrade your air filter too and enhance your wear reduction strategy! just by getting rid of those "oil wetted gauze" air filters, you significantly decrease engine oil contaminates. Please try the AMSOIL Absolute Efficiency air filters which are available in stock, cold air induction, and racing/street rod air cleaner configurations.
AMSOIL's Bypass filters monitored through a oil analysis program have been proven to allow AMSOIL synthetics to maintain proper oil viscosity for extended periods, often beyond 150,000 miles in average gasoline and diesel vehicles. These filter systems save time and money while reducing the potential for used oil contamination in the environment. When using AMSOIL engine oils, generally change Ea Full flow oil filters at 1-year intervals (or 25,000 miles) and the new EaPB every other full flow filter change or 60,000 whichever comes first!

(To just relocate your existing oil filter only - order BMK-14 (more below)) - Simple and low cost.
Vehicle applications at bottom of page with illustration links! See Chart.
The AMSOIL Bypass filter kits come in several variations. When selecting, please see the chart below or call us directly at 1-800-579-0580. We sell several weekly so we can help you get what you need quickly. I personally prefer the BMK-21 for almost all applications. The 23 us the universal dual remote (full flow and partial flow), the 14 is a remote oil filter only and the 25, 26 and 27kits are duel units designed for the main selling diesel pick-ups.
For those wanting to add a bypass filter to smaller vehicles with limited space or if you do not want to relocate your current filter, use the BMK-21 (Overview drawing), which is the bypass only. We have many Volkswagen, Toyota, and other compact engine compartment's housing these.
You save money because you are changing your oil less often! You also help reduce America's dependence on foreign oil.
Improved oil cooling
Your engine will run cooler, which helps to reduce wear on your transportation investment
Increased filtration capacity and life
Your oil is filtered more effectively and efficiently, thus removing more wear particles and reducing the contaminants that cause damage to your engine. Engine life is extended.

PRODUCT DESCRIPTION
The AMSOIL Bypass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Bypass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately ten percent of the oil at any one time and traps the extremely small, wear-causing contaminants and water that full-flow filters can’t remove. The AMSOIL By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil. Useful for fleets and the daily commuter.
Extend oil changes even further with our oil analysis testing. GO beyond 100,000 miles
PARTS SUMMARY
If ordering the BMK-23 Universal Dual Remote (Bypass filter with full flow together) you must order the correct Spin-on Adapter to match the filter thread of your engine. This improvement results in better chemical resistant sealing and easier installation as well as larger hose. See Diagram F in BMK-23 Instructions. Call for price.

New Aluminum Billet Oil Fill and Oil Filter Caps for BMK11 By-Pass Filtration System
AMSOIL now offers new by-pass components to ease the installation of the BMK21 By-Pass Filtration System in three popular diesel engines: the Ford 6.0L Power Stroke™, the Dodge 5.9L Cummins and the General Motors 6.6L Duramax.
Engine compartments are becoming increasingly cramped, leaving little room for after-market additions and improvements. The BMK21 is a single remote by-pass filter system that fits into much smaller spaces than the AMSOIL Dual-Remote By-Pass System.
Ford 6.0L Power Stroke™ Diesels
To ease installation of the BMK21 on 2003 and later model Ford pickups equipped with the 6.0L Power Stroke™ diesel engine, AMSOIL provides the new Aluminum Billet Oil Filter Cap (BK1101), the Aluminum Billet Oil Fill Cap (BK1102) and the 90-degree JIC Elbow (BP242). These new high-quality billet aluminum caps replace the original equipment manufacturer (OEM) filter cap and oil fill cap. The new caps have holes tapped in them that accept the JIC elbows for hose connectors.
Dodge 5.9L Cummins Diesels
To ease installation of the BMK11 in 2004 and later model Dodge pickups equipped with the 5.9L Cummins diesel engine, AMSOIL offers the new 1/8" NPT - 1/4" JIC fitting (BP241), the Aluminum Billet Oil Fill Cap for Dodge 5.9L Cummins diesels (BK1301) and the 90-degree JIC Elbow (BP242). The BP241 fits onto the existing plug on top of the OEM full-flow filter mount, and the addition of the BK1301 eases the installation of the oil return line.
General Motors 6.6L Duramax Diesels
To provide GM Duramax owners the same ease of installing the BMK21, AMSOIL is now offering an oil filter “Sandwich” adapter (BK1201).
The Sandwich adapter is an anodized billet aluminum adapter that screws on to the present full flow oil filter nipple located on the engine block. The full flow filter is then simply spun on to the adapter. The Sandwich adapter has an orifice to provide high-pressure oil feed for the BMK21. Like the other diesel applications, AMSOIL now offers an Aluminum Billet Oil Filler Cap for (BK1202) to ease the installation of the oil flow from the BMK21 back to the engine. To complete an installation, the following components must be purchased separately:
1. Aluminum oil filter Sandwich Adapter with o-ring (BK1201)
2. Aluminum Billet Oil Filler Cap for GM Duramax (BK1202)
3. Two 90 degree JIC Elbows (BP242)
4. Single Remote By-pass system (BMK11)
5. By-pass filter (EaBP90, EaBP100, or EaBP110, as space dictates)
** For all the BMK-21 installs we think it is wise to order the BP-67 oil sample petcock valve w/ street tee fitting.
Designed for use with several AMSOIL Ea filter sizes (Full Flow Filter on right)

2003 Dodge Ram 4.7L engine This By-Pass was installed without drilling any holes and no additional custom bracket or adapters. Excellent and simple install. 2001 Chevy Cavalier 2.2L I4 - Neat compact installation making a excellent car even more reliable while simplifying oil changes for the family. 2002 Jeep Wrangler 6-Cyl. - One of our most popular vehicles to add the By-Pass system to.
Designed for heavy duty work-horse engines that have oil sumps from 16 to 42 quarts. This kit is uses two AMSOIL Bypass Filters (three sizes to choose from). Their unique internal flow spreader and follower spring system provide a non-channeling filter media system. Each Bypass unit contains stacked-disc type elements which has been shown to reduce piston ring and rod/main bearing wear 75% to 91% (Society of Automotive Engineers paper 881826).
It's Convenient: Elements spin on and off for fast, neat filter changes.
Built-In Safety: A metering orifice inside the mount controls the oil flow so that it never draws more than 10% of the oil pump's capacity. At an engine speed of 45 mph, the AMSOIL Dual-Guard Bypass Filter cleans all of the oil in the system every 5 - 10 minutes (depending on engine RPM, sump size, and oil pump ratio).
The BMK-12 Mounting Kit: The BMK-12 kit contains a mount, mounting hardware, a restriction fitting, and two 3/4"-16 to 1/4" JIC fittings (Please see link above with parts list). Complete installation instructions are included, along with an additional parts list of plumbing hose and fittings available separately from us or your Commercial account. Spin-On filter elements should be bought separately in pairs based on sump size or available space in the engine compartment. The following is merely a overview, since the larger the element used, the less frequently it will have to be changed. See actual intervals as tested in these performance tests.
For a crankcase sump of 15 to 18 quarts, use two (2) BE-90 filter elements.
For a crankcase sump of 15 to 30 quarts, use two (2) BE-100 filter elements.
For a crankcase sump of 15 to 42 quarts, use two (2) BE-110 filter elements.
Your AMSOIL By-Pass Filters will last twice as long as your regular filter, so change them only half as often.
Other Applications for AMSOIL's Dual Guard:
Stationary Engines
Large Industrial Compressors
Diesel Electric Generators
Irrigation and Farming motors
Marine
The AMSOIL Bypass filter kits are a low cost way to extend engine life, save time, reduce maintenance and protect the environment.
BMK-11 recommended to replace all Studebaker factory bypass filter units.
As a Studebaker owner I will have some photos and results soon but if you would like to discuss the product we have to upgrade your Studebaker bypass filtration system which is about the most simplest installation possible with these kits, please call me. I would suggest calling to take a current oil sample then after the installation of the kit sample again to see the results of superior bypass filtration.
