Although this is an Oil Website, I think that some people downplay the importance of engine air Filtration in keeping an engine clean...

Who makes the Air Filter with the best particle Filtration? Would it be the Fram Ultra Air Filter? (Only sold at Walmart) or is it another brand I am missing?

Maybe!
But, I don't know if there is one brand of air filter that would be considered "best filtration" due to having so many different applications. However, there is a "higher line" of filtration such as the FRAM Ultra AF you mention, and I think this is where the focus could be.

Depends on how often you want to change it. OE if you want to stick with the factory service interval or for better filtration at a much shorter interval you could look at something such a Micronair Blue by Corteco.

Never mind. I thought OP meant Cabin Air Filter.

Go with a quality filter like a WIX or OEM and make sure the sealing surfaces are perfect.

Many air filter housings are difficult to open up fully and so people spread apart the housing a few inches and slap in a new filter. Better to take more apart and make sure the filter is seated properly.

tests have shown that OEM filter on the second half of their life have better filtration than new ones. A little dirt caught and a little oil vapor makes it a finer filter. It still flows enough to give the engine near full power (how often do you really floor it anyway).

For a regular grocerygetter OEM will work fin as long as it is properly installed and sealed.

OP said, "Although this is an Oil Website, I think that some people downplay the importance of engine air Filtration in keeping an engine clean..."

I must explain my disagreement with notion.

Dirt in the engine air supply is commonly cited as THE source of silicone contaminants in oil.

Also, many have conversationally referred to air filtration as being "more important than oil filtration" for removing abrasives.

In fact, high silicone is mentioned as a red flag to alert heavy machine owners to incorrectly installed air cleaners.

Dirt = bad, ALWAYS.

I am going out on a limb. I think the air filter is more important than the oil filter.

Most cars that come through my shop have a mis installed air filter. Especially astro vans. None of them are installed correctly when they come in the door.

Denso has triple layer construction, Fram Ultra at Walmart if they have your size, and AC Delco are good ones. I like them so that's what I unscientifically think.

Good to resurrect a topic now and then that is long in the dust bin of old topics.

^^ Agree with this...

And it should be a crime how poorly most air filters are installed. You can often blame the quick lube places for that error.

I remember reading that test report years ago and promptly removed the K&N from my 2000 Ranger. That filter has been washed and still in my shed...haven't been able to give it away!
