New AMSOIL By-Pass Filtration Kits
AMSOIL Technical Director Dan Peterson discusses upgrades to the BMK kits.

AMSOIL is introducing significant updates to the by-pass filtration systems in May, offering many improvements to the popular BMK kits. AMSOIL Technical Director Dan Peterson sat down with the Hotwire to provide Dealers with a little advance information on the new kits.

Hotwire: Why make changes to the by-pass systems?
Dan Peterson: AMSOIL is committed to continually improving product performance and customer satisfaction in all aspects of our business. Fresh ideas, new concepts and considerable research led to improvements in our by-pass filtration products. The new kits were designed specifically with Ea Filters in mind and include additional features that provide improved performance, increased longevity and easier installation. The design of the original billet mounts restricted our ability to improve the performance of the overall system. The improvements implemented will help AMSOIL Dealers be even more successful in marketing and selling products in this quickly-emerging area.

HW: What are some of the benefits of the new BMK By-Pass Systems?
DP: Several improvements were made. For example, oil flow has been improved throughout the entire system to ensure the precise amount of lubricant is flowing through the by-pass system while simultaneously keeping the engine protected. This is typically measured in terms of flow (gpm) and pressure drop across the system. Larger ports, increased hose diameter and larger fittings were implemented to increase flow, ensuring full compatibility with all OEM oil pressure sensor systems. In addition, extra hose is included with the kits to make sure most tough installations can be completed without having to order more hose to finish the job. Also, new adapters were designed that are much easier to install and provide improved durability to withstand harsh environments.

HW: Do these improvements mean there will be an increase in price?
DP: AMSOIL by-pass systems haven’t risen in price over the past three years while the cost of their components has risen steadily. With these improvements pending, AMSOIL refrained from increasing prices on by-pass kits when price adjustments were made for other products. Four extra feet of larger-diameter hose and upgraded oil filter adapters have combined with the increases in general components to force AMSOIL to adjust pricing. These upgrades improve the quality and performance of the systems, and even with a price increase, AMSOIL by-pass kits are still less expensive than competitors’ by-pass units.

Q: In the old Dual Remote BMK systems, oil flowed into the by-pass filter first, then the full-flow filter. In the new BMK mounts, the opposite is true. Why the change?
DP: The new by-pass systems were designed to more precisely meter the oil through the system via an engineered flow regulator. The flow regulator replaces the spring-loaded valve in the original systems and requires switching the position of the full-flow filter and the by-pass filter.

HW: Everything we’ve discussed has related to the dual remote mounts. Have there been changes to the BMK11 as well?
DP: The BMK11 is manufactured using a new process that is consistent with the design of the dual remote mounts. There were no other changes made to this by-pass system.

HW: Are the new by-pass systems compatible with the AMS-Oiler™ Oil Pre-Charger?
DP: Yes, these systems are designed to run with the AMS-Oiler.

BMK By-Pass Filtration Kits will have new part numbers as well.
Old Number New Number
BMK11 . . . . . . .BMK21 Single Remote By-Pass Kit
BMK12 . . . . . . .BMK22 DUAL-GARD
BMK13 . . . . . . .BMK23 General Use Dual Remote

BMK16 . . . . . . .BMK26 Ford 7.3L Power Stroke Applications
BMK17 . . . . . . .BMK27 GM Duramax 6.6L Applications
 
Thanks, Pablo. I wonder how long it will be until the website lists the new part numbers. I hope that they didn't announce this without waiting until they had depleted the existing stock of old numbers. How are any of us supposed to sell a product that's going to be superseded "as soon as we get the obsolete stuff sold"?
 
It's only in the DJ news....so it hasn't been announced to the public yet.

Well I guess it has been............now

but not officially by Amsoil.

Man I am glad i decided to hold off a month on my BMK-13! Sounds like a much improved product. This is why I like Amsoil.
 
It will be interesting to see how exactly the workings of these units. I had alway's thought that partial-slow flow was the way to accomplish the bypass method....but, we will see....interesting stuff!
 
Hey Pablo, can you tell me what I would need for my 2005 Duramax and what the price would be? I looked on the Amsoil website, but it was a little confusing as to what application, etc.....thanks. Also, what is the difficulty level of installation for someone who does all of their own mods and work on their own truck, namely me?

It depends on what type of system.

If you want just a "stand alone" by-pass - (take oil from a pressured source and return it to a relatively lower pressure area) then you need a BMK21 Single Remote By-Pass Kit. Currently $174 MSRP or $130 PC, but may go up a tad.

If you want to relocate you full flow filter mount, wait for the new BMK27. Currently they are $235 MSRP or $183 PC, but may go up a tad.

PC cost is $20/year.

If you do medium level or above mods, then a remote bypass will be a piece of cake.
 
The one I have seen on the website is the system that has two filters coming off of the factory feed via two lines (the send and return line). Which system is that? I want to start going longer intervals. I currently go 10k with medium duty use and no UOA, but want the bypass and will start using UOA. Even if it only gets me to 15k intervals, I still want the added protection. Oh yeah, I do have PC.
 
Great Info, Pablo. Thanks for posting.

It will be interesting to see the benefits of an "Engineered Flow Regulator" over the spring loaded valve currently used on the BMK-13. A flow regulator would likely restrict some flow through the bypass filter when cruising down the highway with a hot engine, while the current ball valve permits as much as possible to flow through the bypass filter under these conditions.
 
The original bypass filter they had was simple and effective. The elements were too expensive. The ideal bypass filter takes a small amount of dirty oil from the high pressure point of the oil system, cleans it and returns the clean oil to a low pressure point, such as, the oil pan. I do like to use a sandwich adapter. The best place for the full flow filter is almost always where the factory put it. I saw a dual remote system on a Duramax. What a joke that was. Put a sandwich adapter on the filter mount. Screw a stock filter on it, run a couple of hoses to a submicronic bypass filter and you are done.
 
I agree with Ralph, these new systems are a tad-bit extreme. I looked at Mann's install of the dual mount remote filter and I personally would just install a simple, partial flow bypass filter on my rigs. Even using Amsoils parts and filter this can be achieved for under 60.00.....These new systems are designed to do-away with the stock full-flow filter....using Amsoil's system and keeping the same rate of oil flow as the OEM> This way it does not mess with the oil pump. The partial bypass is still in my mind.....the way to go!
 
Well, I finally bit the bullet and ordered the Bypass System from Amsoil. Should be here Thursday...........I bought my truck with 60k on it 1.5 years ago. It now has 94k.....I figured it is worth the money with all of the hauling and just daily driving, not to mention getting the best use of my synthetic oil.

Did you get the new system or is it the old system?
 
well, unfortunately, I got the old system. The new one was $55 more and the old one seems to be just fine. I had a budget and the old system met that, so I had to go with it. Just came in today.......now for installing........ooooohhhh yeah!
