When going with the 6637 filter, is there any reason you would need to put the Filter Minder back.

 

It will still be useful in letting you know when the filter is clogged up.
That event will most likely happen well after you have had the filter in there for a long time and it's getting very dark looking.

 

Half the time the "filterminder" doesn't work correctly work. I wouldnt worry about it

 

Yea I wouldn't worry about it - it would be one thing if the filter wasn't visible - but it's right there in plain sight. I gotta believe it would have to look pretty ugly before the filterminder ever moved!!

 

Just wanted to know if was worth the time of finding it and sticking it in the end of the filter. Doesn't sound like it would be worth it.

 

My filterminder always seems to show the filter as clogged. I can put on a new filter and in only a few thousand miles it will show a clogged filter even though it is a practically new filter. So, I don't really pay much attention to it.

 

i would not worry about it. they never seem to work right. its always hit or miss with the filter minders.

 

Mine never moved, so I figured it didn't work right. THEN I drove through a sand storm while camping in Glamis... As soon as I hit the freeway, it sucked right in and lit up my dashboard light. My filter was FULL of sand! But NOTHING got past it (white rag inspection). The Filter was a Baldwin.

 

When did they start putting an indicator light in the dash for a dirty air filter? I sure as heck don't have one.

 

Apparently in 2002.. Here's images directly from the 2002 7.3 supplement. There was no indicator in the 2001 7.3 supplement.

 

I've noticed a lot of diesel owners could use some info on how to use their Filter Minder. The Minder is just a messenger, and is only telling the vacuum level on the clean side of the air filter. Depending on how it was engineered with the air induction system, with a new filter it may show zero, or may be up a notch or two. This is the clean filter restriction level. The typical air filter takes a long time to show any additional restriction from dirt/dust. It may take 50-75,000 miles depending on operating conditions. If you pull a filter and look at it, it will look dirty...........that's it's job !!!! In fact, it filters better than a new filter if it has a dust film. If you don't see the Minder go up, there is no increased restriction. If you change to a different aftermarket filter and see a difference in the Minder reading...........it's just telling you if that filter is more or less restrictive. If it goes all the way to red zone, you may want to think about what type of filter you just installed, as you've just increased the restriction in your air induction system. We've been taught for so many years that we need to constantly change air filters, and that's just not true. Many air filters will last 100,000 miles or more. If you just like changing filters frequently, that's fine, but don't blame the Minder. For more information go to www.filterminder.com

 

Good post hope31.

 

Hope,

One thing we've noticed is that people installed them back in the side of a filtered air duct. That causes the air rushing by to produce an unrealistically-high vacuum on the FilterMinder port due to the Bernoulli Effect.

I'm a big believer in FilterMinders, as mine has indicated properly for me when a filter needs changing. I believe those that have had trouble with them, or think they don't work, likely aren't using them properly.

I re-installed mine in the fender end of my 6637.
