I have one and use one but are they really worth using on a gasoline engine or any engine for that matter?Thanks Joe
FilterMinders-Are they worth using?

sure, it will let you know when your filter needs changing. I have about 20 of them if anyone needs some.
They are standard on some of our fleet trucks.
An air filter lasts longer than most people think. And a minder means we change them when it's needed.

a filter minder costs less than an air filter and will probably save you from changing multiple air filters early throughout the life of the car. i think it's a good investment.
not to mention you aren't messing with the air filter more often than necessary and spilling dirt into the intake.

what? Never heard of these? LOL....pics? Are we talking a "computer esque" 'minder? Similar to that of an oil life monitor? 
Or....?
But that brings up a good point
Shouldn't the engine know when it's being "restricted" by say, dirt.....dust, etc.?
Or....?
But that brings up a good point

Here is the Wix gauge I use and its cheap at $13.95

The same Wix filter restriction gauge is available from Amazon for the same price, and free shipping if you buy something else with total of $25 or more. Amazon has a "used" one, actually repackage, for only $7.07 and it's eligible for free super saver shipping too.
Dually, I think you got your answer.
Consider this also. It comes from an engineer who works in the air filter industry:
"Ninety percent of the dirt ingested by the engine during the filter element's life comes in the first 10 percent of use."
People who change filters too often are letting more dirt into their engines than those who run them longer because filter efficiency improves with use. It gets better and better but at some point, restriction begins to take a bite out of the power output. The restriction gauge allows you to determine the EXACTLY CORRECT moment for a filter change according to the operating environment of the vehicle, whether that. sin 2K miles and six days, or 5 years and 90K miles.

I think that air filter restriction gauge(AFRG) should be standard equipment in all engine. Of the two AFRG and TPMS, AFRG is much more useful.
I'm going to talk to a mechanic friend about them (I think that they are great).
Could do a simple photocopy attached to the invoice, explaining that they will know when to get the filter changed, rather than a standard 5-10k $20+labour.

I have looked at these threads with interest, such things are not common, perhaps they Are in heavy haulage or other commercial environs.
But they would certainly ensure the full life of an air filter is used.
I may have a look under the bonnet of my cars to see if there is room to fit one.

Some class 8 trucks usw the filter minder and some use a plain old vacuum gauge. Personally I prefer the vacuum gauges.
Sorry, I meant to say not common in the UK!
What exactly are these measuring? Is it the pressure differential to ambient?
So it should be possible to get the same information using barometric vs. MAP sensor data?
I know you have mentioned it before but what max restriction?

It would work on a diesel because it has no throttle but not on a gasser. The MAP reads below the throttle and the throttle would skew the readings. In fact, you can't use a restriction gauge at all on carbureted engines because the operation of the choke will skew the readings... so I was told.
Max restriction is decided on an individual basis according to the engine. I have seen some diesels as high as 30 inches. Generically, many sources list diesels at 25 inches of water and gassers at 15 inches. Ron Kelderman at Filterminder thinks that for maximum FE, diesels should be limited to 20 inches.

For me they are definitely worth it. I have one real life example on my site with one of my delivery vans.
First OEM filter: 12 months, 23,900 km
Second OEM filter: 7 months, 15,500 km
Third OEM filter: 17 months, 38,500 km
Current OEM filter has about 20,000 km on it in about 10 months
It depends on the humidity, dust, smoke, and where it goes for deliveries. first filter came on it, next three wer bought at the dealer for about $40 each.
What interval would I have used if not for the sensor?
