Air Filter Restriction Minder

Never had one that worked, but I've discovered WOT on my 120 tune will suck that baby all the way into the red.

Open air tymar comming up..........:Thumbup:

So at least they do work, even if not for what it was intended!!

'00 cc f 350 a few mods, and a bts tranny.

Those things are useless on a truck IMO. It is one thing to need them on machinery working in hugh dust applications and you need to know immediately when to change the filters. Although on a truck when most people change by mileage, they are just not needed. Not to mention like you said, most of them do not even work.

I noticed mine weren't accurate without an explanation of why. We have these giant dragon fly type bugs in May called lake flys (short for fish food) as well as moths all summer. All you need to do is drive right before dark to get a mess of them stuck in the filter. After dark it's all clear and you don't see them. The "minder" doesn't move. It says never mind to them, ignoring a hat full of crispy bugs as big as your thumb.

Here is a story, truck pulls in shop customer says its using oil but no leaks,runs ok. plug the diagnostic machine in no codes, check the filter bowl for signs of oil in fuel looks good. look at exhaust and tubo for signs of oil nothing. so i look at the filter minder it looks ok still in the yellow. pull the air filter box top off and holy s*** , the filter was a nightmere bugs, leaves,dirt,mud yes thier was actually mud stuck to the under side of the pleates,paper and some how a brown paper bag???? . now i look down the intake tube at the turbo and ccv tube and both are coverd in an oily mess. the air filter was so pluged the engine was pulling air from the ccv tube,along with some oil. so for fun and to learn i put it back together. start the truck and here a vacume leak look around and it was coming from the oil dipstick tube :roflmao: hard to beleave it but true! it did run rough but it ran. after i kleend the air box and installed a new filter i tell the customer NEVER EVER TRUST THAT CRAPY FILTER MINDER!!!!!!!!!!!!!!!

I saw a shop towel once and some mud bees, but nothing like that. :roflmao: Makes sense, the open air elements flow more and suck more oil in with the air. Sounds like Christine...cut off it's air flow and it makes it's own air inlet. :evil:

I had a restriction minder on my Tymar intake(just to see how it does). It seemed to be worthless. That filter is so big that only if you where to shovel mud on to it may show something on the gauge. I think that you just don't need it. All you need to do is to look at the filter once in a while or after you've been mudding or gone threw allot of dust. just use comman sense.:Thumbup:
