I don't see how the filterminder can work as it was designed with the 6637 filter; it was not made to work with it. The air flow is much different than that of the stock intake, don’t think you would be comparing apples to apples due to the increased air flow.

I just left mine off... don’t see the need for it.

Just my 0.02

 

Well that's most certainly not a safe assumption, but it does indicate that you didn't bother to click on my reference link, because if you had you would've seen an extensive discussion of "Bernoulli's Principle", and why it has at most a second order effect on the accuracy of Tenn's CFM vs restriction measurements which employed a simple right angle fitting at the neck of the 6637 filter, which is also the correct placement for a filter minder to get the correct reading to monitor filter restriction. From post #65... In the following post #66, I gave a detailed explanation of "Bernoulli's Principle" using a "swarm of bees" to aid the understanding, as well as equations and more precise mathematical models. In post # 78 I gave yet another explanation of "Bernoulli's Principle... ...and calculated its effect using this approach.

I respect the right of all FTE members to post their beliefs and opinions, however, when they're incorrect as the above are, and when they're presented as authoritative advice for others to follow, and when such advice might do harm to other members PSD's, I try to set the record straight!

They're many in depth discussions in the link I gave discussing why the correct location for a filter minder is at the neck end of the filter, for example...

 

Well, ya' got me Ernie! You musta' proved your point, as I am now so befuddled that I will defer to your better judgment. (Tucking tail between legs.)

I'm obviously out of my league.

Sometimes, twenty seven eight-by-ten color glossy photographs with circles and arrows and a paragraph on the back of each one explaining what each one was, IS good proof!

Good enough for me...

the filter minder was not designed for the 6637 or any other filter system specifically
it was designed for any and all air intakes to show the basic condition of the air filter
the filter minder its self doesn't have to be munted to the filter or intake ,it can be mounted at a remote location with a tube run to it

• The Filter Minder ® is installed on the air cleaner or air induction piping so that it has access to clean filtered air (between air filter and engine).
• The air filter service indicator is a simple device that accurately measures the air induction system filter restriction. It measures and remembers the highest restriction at maximum air flow, which is called full load condition. This condition occurs during hard acceleration, or while pulling a trailer, etc.
• The indicator is easy to read. As the air filter plugs, and restriction increases, the yellow position indicator moves in the clear window and locks at several points. When it reaches and locks in the red zone, the air filter should be changed and the indicator reset to zero. Reset the indicator by pushing the yellow reset at the end of the indicator.
• Another type of air filter service indicator is the Filter Minder ® Single Position Service Indicator. The clear window turns red when maximum recommended restriction has been reached.
• Every air induction filter system has a clean filter or initial restriction reading. Depending on air flow volume, filter media, and air filter size, there may not be enough restriction to show a reading on the gauge with a new filter, or the position indicator may move one or two positions. Do not be alarmed if there is some restriction with a new filter as this is not unusual.
• Air filters usually show low restriction through most of their service life. As the air filter nears the end of available service life, filter restriction will increase more rapidly, and the yellow position indicator on the Filter Minder ® will move more rapidly towards the red zone. High humidity or rainy conditions may slightly increase air filter restriction.
• The Filter Minder ® is calibrated in inches of water vacuum per the engine manufacturer's recommendations.
• Use of the Filter Minder ® helps maximize filter service life, prevents excess fuel usage from overly restricted filters, and saves on operational costs.

rbaker6336 i understand what you are saying. With that, i am still going to leave mine off.

 

That's good info, and it gives the proper location of a filter minder, and some good reasons for having one, however, it failed to mention the most important reason, namely to avoid filter collapse! Again, the following is all from the link I provided earlier...

 

Thanks for the acknowledgment, I'm not trying to pick fights, but rather to analyze and explain things the best I can, as that's become my retirement hobby. In the link I gave, I responded to a number of posts that made incorrect assertions, but none of those members bothered to even acknowledge my explanations.

As I explained in the link, mounting a filter minder where you suggested is better than not having one at all, but the filter needs to become fairly restricted before a gauge placed there will give a reading. When Tenn had his tap in the end cap, I suggested a test to illustrate that if a 6637 is sufficiently restricted, a filter minder located at the far end (instead of the neck) can still detect some restriction.
