If you REALLY want to be confused, put "compare truck air filters" into your search engine and count on spending unlimited time getting conflicting
info & hype (but Harald's test was there, too)! Then I went to several Auto Parts stores and nobody has the AC Delco air-filter I need, and it
will take a week, or more, to order it in.
I finally went outside, and just hand-cleaned and re-oiled my K&N filter with their "cleaning kit", and hope for the best. (It was really
dirty----very embarrassing).

MANY of the filters that Napa sells in their Gold line............are Wix filters.
Good paper filters.

Filters
My self have never been a big fan of K&N filters.. Seen Many,Many dirty ones,,, Too much work... fresh paper is the way to go for most apps and
formy Volvo I use a MANN brand that has the check valve and you can level a RV with one.. WIX are fine...The ONLY way to clean a MAS/MAF is with CRC
MAS/MAF Cleaner.. do NOT use carb cleaner,break Kleen or anything but the correct stuff or U will be replacing the sensor soon and they are not
cheap..

The Captain is right on this one. I performed the experiment he is warning against on one of my Kia's, resulting in a ruined mass air flow sensor.
The symptoms were; Easy starting when cold, but slightly rough, progressing to misfiring badly after I got a few miles from home, mostly in the mid
range rpm.
They are expensive, but the one on my parts car swapped out just fine, and is running to this day.
If you are not living on the edge, you are taking up too much space!
"Could do better if he tried!" Report card comments from most of my grade school teachers. Sadly, still true!

We have not had the problem with ruined air mass sensor. From K&N filters,but every truck we serviced. With K&N air cleaner carb,or intake
runner full of dirt. On dirt bikes,carb slide sticks wide open from dirt. Only with K&N air cleaners,We wont even buy a used truck. If it has a
K&N air cleaner.

The MAF just need to be cleaned, they
Y aren't ruined. Buy some of the cleaner mentioned above and it only takes 5 minutes for it to be like new.

Just my personal experience:
My 22 year old 1994 Ford F-250 4x4 with the 460cc engine has had a K&N air filter on it that entire time with no problems with dirt getting past
the filter as near as I can tell. The truck is ONLY used for trips into the boonies, mostly on dirt roads in Baja, and has 85K miles on it. Nothing
has ever gone wrong with this truck other than having the AC unit recharged about 10 years ago--------it's been a dream truck. (horrible gas mileage,
however----10 mpg no matter what)

Last time I went to service my K&N filter, I noticed dust coating the throat of the throttle body.
I held the filter upto sunlight and there were pinholes everywhere.
The K&N lovers came out of the woodwork and accused me of cleaning it with a wire brush, or cleaning it with acetone, or a sandblaster, or other
similar ridiculousness in their refusal to believe that their upgraded well marketed 'filter' was not effective, as a filter. perhaps a rock and
pebble catcher.
I threw it in the trash and went back to paper, disgusted that I had fallen for the marketing 10 years earlier.

I just went out and held my K&N filter up to the sun--------no pin holes, and it was uniformly clean (now), but yes, the sunlight does stream thru
it opaquely (sp?).
Perhaps it's all those micro "pin-holes" that allow the air to pass through it so easily, but like the Captain says, it does not help the 460cc get
better gas mileage--------I think that is a hopeless cause expecting better gas mileage from THAT dream-engine-----there are always a few down-sides
to everything. LOL
Having said all that, I have (or will have) AC Delco paper-filters on all my other rigs and cars, so you see I am not completely hopeless. (just too
cheap to throw away an expensive K&N filter).

My AFE filter cost about $60 5 years ago. I tap it clean every oil change (10k miles) and it is warrantied for life. It has never been black like in
the foto above. Just a little dust. How many paper filters will you change out over the rest of your vehicles life and at what cost?

My dad's last car, a 1973 Ford LTD Country Squire station wagon had the 460 engine, and he loved it! He had a second gas tank installed as well as air
adjustable rear shocks specifically for our July 1973 trip to Loreto, before Highway One was completed. I remember we ran out of gas by Rancho San
Martin, south of Santa Ynez and he switched the lever for the other tank fuel line. It took a while to get the fuel flowing again. From north of Santa
Ynez to Laguna Chapala we were on the old road as that gap had not yet seen the bulldozers and graders for the new highway roadbed.
Here's a photo from that day, in the Laguna Chapala valley on the new roadbed and one I took from the road bed of the detour next to it... That was
Chapala Dust... famous in the pre-highway days.
The mighty 460 cid engine pulled us through!
At the top of the pass, south of Chapala, congratulations to my dad were in order.
My mom and the new highway construction behind her heading south to El Crucero and Punta Prieta:

Thank you. It was that summer 1973 trip that inspired me to write my first guidebook, I was 15. I loved taking notes on the mileages along the way.
We drove the road to Cabo in 1966 in a Jeep, and I remembered it well. So comparing the new highway route with the old road down Baja was very
interesting to me.

Oh oh, Woody------now you are going to start another disagreement, I suspect. You say you oil-change "every 10K miles"? I change oil (it's cheap)
every 3 to 5K miles, just to be safe. My son is still driving my old stick-shift '69 Ford F-100 and it's going strong (240ci 6 cyl. engine) that we
both have religiously changed oil in every 3K miles. That engine burns 1 qt. every 3K miles, roughly, and is in great shape. (frequent oil changes
equals cheap insurance, I believe)

Well, I spring for the synthetic oil. Blackstone labs tested a sample years ago and said to go 10k. Other Tundra owners I know go 20k between changes
and their tests come back good. 10k for me is about 20 months. Oh, with zero burnt oil. Drain 7 qts and add 7 qts.
Edit to say modern engines have much tighter tolerances so the need to drain "dirty" oil doesn't happen until much later, especially with synthetic
oils.

K&N filters let a lot of air into the engine. this is accomplished by large openings in the filter medium. this also allows lots of dust and crap
to enter also. this is great for a race engine at WOT that will be rebuild at frequent intervals. i don't use them.
