Meh, it is a good filter. You won't notice a difference in flow in the seat of your pants. Keep that K and N serviced nicely and your old tractor motor will be just fine.
Folks like to take this stuff a tad bit overboard.

I agree, the K & N isn't a bad filter. The stock filter has a lot of surface area, so pressure drop across the filter isn't much and velocity through the filter media is pretty slow, so it would be difficult to improve performance that way.
Just maintain it.

K&N is a great filter. I havnt used one in 20 years but from my past experience, it did prove to work very well when I lived in the desert southwest. Bring the cleaning solution and oil to clean it if it gets plugged. A garden hose with a pressure nozzle aimed at it from the outside pointing into the center will force out the particles.

I've never heard of K&N being an issue on 60/62s. On 80s its a definite no-no.

Why is this a 'no-no'?

I've used a K&N off road and were there another good choice for that vehicle I would round file it immediately.
The issue is not flow unless you're talking flow of grit. I've done everything that I can think of to stop grit from showing up on the INSIDE of the filter. Things like greasing the filter's rubber end seals with heavy bearing grease etc. Nothing, absolutely nothing would stop the grit from appearing on the inside of the filter can. Running the filter sloppy messy dirty helps a little bit, but not by a lot.

Nice tracks of moab red dust running down a carb are why I am not a great fan of K&N's..
Oh yeah, one more thing. On trucks that use a MAF, if you over oil the K&N it can put droplets of oil on the air flow sensor, jacking the computer up something fierce..

Which is the reason Ford won't warranty replace the MAF on one of their vehicles if you have a K&N.
Good thead...
X2. i've run k&ns for years. it kinda makes sense that they might be a problem on newer motors since a lot of people tend to over oil them, but on your motor, it will work just fine and save you a ton in filter $$
I ran a k&n for years, in moab, and never had trails of dust inside my carb
on the outside, i don't care....the outside's gonna get dirty whether or not there's oil there.

I have run them for years and honestly was skeptical untill this year's moab trip. we did hundreds of miles of driving on dirt roads prior to and after the event and even though the outside of the filter was literally caked with red dust, the inside was spotless..
that's just me though..

Lots of test out there for filtering ability of the K&N compared to a paper element.
Consider this tho. Most off road racers do not use K&N's they use large paper elements..

lol
Overboard is "OH MY GOD IT WILL KILL YOUR MOTOR!!!!!!"
lots of old tractors use oil bath air cleaners...
let's compare apples to apples here
btw, wondering where you're getting your facts
i'm finding a lot of off road racers using k & n.

From racing with BITD and SNORE.
A. Oil bath air cleaner does not equal a K&N
B. How many modern tractors use an oil bath air cleaner?
Your statement is similar to suggesting that a old Siamese port Cruiser motor replace the 2F.
Even K&N recommends that you shield the air cleaner if you are in dusty conditions.
Do some reading. Increased air flow without increasing the actual filter area has a cost.

BTW, I have also seen filters clog faster because they are of the oiled gauze design when a large paper element has survived.
Honestly I could not care less if you believe me or not. It's entirely up to you.
Personally, I am not a fan of K&N's.
But, I don't like snorkels on trucks that don't actually cross rivers either..
I did some dry side driving a few years back in powdery dust (and maybe a little Mt St Helens ash) and found the inside of the air cleaner with a nice layer using a K&N. My personal preference is just the paper ones and check regularly.
