Best Air Filter

Does anyone happen to know which replacement paper filters flow best. I looked at a K & N under a microscope and I can see why dirt gets by. There are large gaps, the k & n doesn't come in contact with enough of the air to nab all of the dirt particles. What's your favorite paper filter?

the fram is by far the worst at trapping dirt and such, put it under the scope and see what it looks like.

If I couldn't get a Motorcraft, I use the Purolator.

Purolater make nice filters. I read that the cheapo Pep Boys "Proline" filters are actually rebadged Purolaters!

The more negatives I hear about Fram makes me laugh. I have never had a problem with them but, I prefer the Purolaters...

Wix's are good filters, we use them on our industrial equipment.

I won't use anything BUT motorcraft FL-1A's on my Ford trucks though. Can't beat the ability to buy them for $1.99 @ Walmart.

An oil change costs me exactly $11.52.

gotta love wal-mart, I usually get the fl1a filter and whatever oil is on sale. I use either deutch, or motorcraft air filters.

I think it helps a bunch I actually read the article well!

Walmart doesn't carry the factory Motorcraft air filters, although I'm fairly certain they do carry $1.99 air filters, I wouldn't want to run it in my trucks.

That is why it uses oil. A dry k&N will let lots of dirt by.

On our 96 i found the following:
Fram doesn't fit the box well (gaskets are too large); the "lid" doesn't seal tight).
Wix fits well.
Motorcraft fits well.

Im no expert but based on these threads if the K&N uses oil I would say its the best,but then I wouldnt think it would last as long.

Its more like 9.95 every year or 2. That kit will clean an average size filter about 3-4 times. I have a K&N filter in everything I own, and I can honestly say that every vehicle gets 1-2 more mpg. They may be pricey, but I still say they are the best.

yeah, but you probably don't drive 70 miles a day through farm country either.

Thumbs up Best Air Filter

As a building conttractor I drive mountain dirts roads almost everyday, and around our place to boot. I pull everything from our horses, to heavy equipment and I also get 1-2 mpg more using them. The first time I drove a vehicle with a K&N type filter was a Ferrair 312P Formula One race car. The foam and oil filters have been around a long time and do work quite well.
I like to clean my filters frequently due to the dusty environment that I drive in. I found that good old 10wt oil works very well and is far cheaper than buying the kit. I use kerosene to clean the filters instead of their kit stuff. Of course you must let the filter dry well before reinstalling it in your vehicle.
Fram is also a fine filter to use, they started out in the racing world first and have proven there worth.
