Is the clean side of your airbox dirty too? (1 Viewer)

[Markuson]

This is a great idea. Also available on Amazon:

Amazon product ASIN B000E5XQDY
Edit:
OK, I don't get WTF is happening, but I can't get the Amazon link to work, something is changing the URL back to the main page. Weird. Anyway, just do a search on "K&N 85-2445".

Hey @KLF ...The same link problem happened to me when I just now used Amazon’s share...copy link feature. Posted here...but it led only to a generic page.

so then I sent the link to myself...posted that...and it posted here as normal.

So...I think something about Mud may be misinterpreting the link...or more likely, Amazon’s update is spitting out a weird link with their copy link feature.

But anyway...
Here’s one....but there seem to be about a zillion companies making these same basic units...with just size, shape and matkings

Anyone have any insight on why one is better than another?

If everyone eventually gets these and installs.. while you have it apart can you snap pics of your carbon emissions trap? I'm curious what others with more miles look like.

Beyond that, I kinda feel like a filter minder deserves its own thread. Not that I'm getting pissy about off-topic.. it's relevant. Just that it will probably get more eyeballs.

And now the link is working properly in my previous post. Even weirder.

Be aware that the K&N one I posted goes to red when the vacuum restriction hits 10" of H2O, whereas the Wix one you posted maxes out at 25" of H2O. I guess that means the K&N one is more sensitive. I ordered the K&N one and will give it a try. Maybe @gaijin can shed some insight on which one is the better choice.

Funny... I had already sent @gaijin a note asking.

There are so many...

I’m lazy, best I can do at the moment. 09, 110k miles. Definitely appears more white than yours.

I tried both. They are all made by Donaldson, but branded to other companies, and with differing specs. The two most common automotive applications appear to be the 11" H2O Max (K&N) and the 25" H2O (others).

The first one I tried was the 25" Max. It never showed any significant increase in vacuum - i.e., it never showed any significant restriction. When I investigated further, turns out the 25" Max model is designed for diesel engines which have higher intake manifold vacuum than gasoline engines.

The second one I tried was the 11" Max K&N model - works like a charm. It is truly a "Run it 'til it hits the Red" indicator.

Here's an Amazon link to the one I settled on: K&N 85-2445 FilterMinder on Amazon

Perfect! Thanks!

Ok so the Filter Minder showed up today, I went with the K&N one that @gaijin recommended. Pretty slick, very easy to install. I didn't like how it crowded my second battery if I put it in front, so I installed in the rear of the upper airbox. I pulled it off the truck to drill the 11/16" hole (step drill), so I could shake out any little shavings that fell inside. Push the grommet in, then the filter, put it all back together. Very easy.

My air filter is in pretty good shape, so the Minder barely moves, but I'll keep an eye on it.

What color was the charcoal trap in yours?

Any dirt in the upper airbox like the thread title?

It was a very light gray. Inside of the upper section was pristine, not a speck of dirt. OEM filter, I believe about 10K miles. Truck has ~63K on it.

Nice!
Mine came today too, but not in yet.

My rig got a new OE filter recently and I remembered watching a review of an Aussie VDJ200 where the owner mentioned the stock airboxes being bad about letting dirt bypass the filter. Wondering if this was a problem on the 3UR-FE I took a close look.. and didn’t like what I saw.

What you are looking at is the “clean” side of the upper airbox. The light material up against the corner is dirt that is presumably bypassing the filter and getting into the engine. This corner was the only spot with obvious dust on the clean side. I believe the crosshatch material is intended to smooth the airflow into the MAF sensor. And I doubt it is that brown from the factory. I haven’t done used oil analysis to see what the Si numbers are.. but from my diesel VW days I remember UOA being good at finding issues like this.

Always OEM filters. This one was about 20k miles, installed correctly, all clamps secured, and yes I made sure the rubber gasket was clipped onto the lip of the plastic filter housing. It can come loose if you aren’t careful.

When I put this filter on I was sure to clean up the upper airbox to make this a valid experiment.

Has anyone else had this issue? Can someone with a low-mile truck take a pic of their upper airbox mesh to show the color?

I’m considering a foam or rubber shim on the lower edge of the airbox gasket to put more pressure on the upper edge.

Thanks for any insight

I took my airbox apart today to clean the MAF sensor. The secondary filter is dirty, not quite as dirty as yours, but not the egg shell white like the other picture.

Is there a way to clean these?

Recommended fix? Just use the non-silicone filter lube?

I’m pretty sure I can get the evap filter out and back in without damage but can’t come up with a way to clean it that I’m sure won’t impact how it does it’s job.

I did get the filter grease but haven’t installed it yet.

 

[bloc]

A couple thousand miles on the new air filter before I got the grease installed. No new dust inside the air box.. maybe a fresh filter and associated gasket does a better job.

 

[Sandroad]

Just a quick cautionary note......if you have the filter replaced at the dealer, don't assume they've used OEM. At one of the "free" service intervals, a local dealer installed an el-cheapo aftermarket filter that definitely did not seal well. Look for the OEM part number on the filter.

Mine is clean. And I ripped that hydrocarbon filter out too.

And I ripped that hydrocarbon filter out too.

Why in the world would you do that? It is not restrictive and provides another layer of dust protection - not to mention performing the function of limiting emissions.

Just curious.

TIA

Appeared restrictive to me. No need to be there on a modern car where ignition is stopped by removing fuel from combustion chamber.

Also removed it on my V8 4Runner 200k miles ago and no issues to report.

Considering these engines are published to make 381hp while adhering to rules that mandate the use of complete copies of intake and exhaust systems when they measure those numbers.. it must not be too restrictive.
