When to replace a reusable air filter in a superduty truck?

I would replace it with a stock paper filter.

Good luck,

Yikes...this is the first I've heard that. This is my first truck, bought it when I decided to go on the road and the impression I got was that this would be the best option. So what's to be done about the dust that's already in the engine. Will that clear in time? I will replace it and see how it sounds.

It is a 7.3 and not a 6 if that makes any difference.

Any dust that entered the engine left a fraction of a second later. Probably did not leave anything behind. . .

You can tell how well they are working by how much dust is left behind on the filter. If the filter is going 10,000 miles without getting dirty, then it is not stopping much dust.

I work in the air conditioning industry, and see the different between good and poor air filters in how much dirt is left on the cooling coils. If they are really dirty, and require a couple of hours to clean them, it indicates they saved $20 on air filters over the past year, but will spend $200 to clean the coil, fan wheel, and the rest of the system.

With good care, and proper pleated air filters, the HVAC system should need air duct cleaning every 8-10 years.

Good luck,

Fred.

It's subtle...kind of a lower growl than usual...feels like it does when the filter needs cleaning but the filter itself doesn't look too terribly bad. I'll try it with a paper filter and see how it goes. Thanks for the input.

Engine air or cabin air. Replace once a year regardless. Just for a question....when was the last time you changed oil?

3 days ago. Always do that on time.

Since you didn't care about proper air filtration when you put it in, why do you care about it now?

Here we go. :S

Yep. Some people use this site as therapy. Never had the courage to do their work, seek out someone to heal the wounds, they just act out in cowardly anonymous ways. Can't imagine what their loved ones go through.

"Everything we do is either an act of love or a cry for help"....

Block, block and block.

You know, proper moderation could completely change the tone of this forum, which is one of the worst I've ever encountered. I can pretty much count on this kind of thing every time I ask a question. Which is to say I can count on being abused every time I show up here to ask for help. Is that the goal, Folks?

I had a K&N come on a used car I purchased. First oil change I replaced it with a paper filter and trashed the K&N.

No perceived loss in performance.

I wonder why K&N filters are not OEM on any car or truck that I can find. That really tells me all I need to know for my normal everyday vehicle.

Thanks!

Not really answering the original question, but re-useable filters, as a rule, are mostly for people with too much time on their hands. Factory elements will often go for 5 times the interval with the same resistance that builds up so quickly with a reuseable. That is because it has 5 times the filtration area. In one comparison that I did, the factory duramax element had 20x the fiultration area of the KN counterpart. It also had a superior filtration efficiency for the entire duration. I would likely never find a case for owning one.

I have an old reusable K+N air filter on my '78 Yamaha SR 500...big single. I just clean it per instructions.

I don't see why or how a reusable filter isn't working as it did when original, unless you're not unclogging it fully.


Only thing I can think of.

I think my K+N was guaranteed for a million miles, but I could be wrong, as I bought it in 1979 and don't have the packaging anymore.

just like internet and bad slides in trailers...

refrigerators and need of prefect balance/level.

10 with problems. and 10,000 with no issues.

or engine oil. trailer tires.

my opinion.

you want issues...
Oldsmobile Diesel car engines. 350
Oldsmobile Gas engine aluminum rocker arm towers.
Cadillac 8-6-4 engine. (Fires)
Arco Graphic motor oil.
Chrysler "Lean-Burn" computers.
