I have the Ford AIS on my truck. I glance at my filter minder when I go under the hood it's always been ok and I have never seen the dash indicator on.

I dated the side of the filter with a sharpie when I changed it last and when I pulled it today it was 3-22-13.

My operating conditions are as follows.

Little to no towing.
50/50 Highway/City
No dirt road or dusty conditions
10K miles per year

Thanks in advance for your input.

Mine never moved either for years. I would just inspect the filter and replace once a year to be safe.

 

Those filters are good for about 60K miles. They hold a lot of dirt.

 

Filter minders are not accurate indicators of the health of the filter.

 

The information with mine said 30,000 miles or 3 years. I just changed mine a week ago. Big improvement. The filter minder hadn't past the first line.

 

I reset mine every time I raise the hood. If I get on the gas it pulls the indicator all the way over.

 

Exactly.

To the OP, you're barely driving your truck. Takes a lot of miles to fill that filter up.

Actually..... yes they are.

Depending on the filter of course.

They are very accurate with stock filters. And with certain aftermarket ones they work pretty well.

My 7.3L had the AFE Stage II intake with a sock over the filter. The filter minder was very good about pegging out when that sock was dirty. It got to the point I could predict the mileage when it would light up the dash, and it was dead on when it needed cleaning.

Your experience may differ, but the filter minder worked perfect for me.

 

mine seems to be pretty accurate as well, but I don't know if the cracked bits on the filter box would have any effect either

 

Under filter cartridge - no biggie. Above filter cartridge - disaster.

My AIS (stock truck with tuner) would suck in its gut at 20,000 miles in a dusty environment. That was once per year when I owned the AIS.

 

stock air box that was all cracked and leaking set of the warning light 2 months after i bought the 02. i put a 6637 with filter cover on, and 60,000 miles later it was still in perfect condition when i put a new filter in and the old filter on the 88. i change and wash the cover every 6 months.
