Thanks for the diverse and informative responses guys.

The Jury is out !

I have K&N filters in both my FJ (in the stock air-box), and in my '95 Firehawk........and I have never had any horrible issues with them........

I can tell you that the K&N filter that is in my Firehawk, is the one that was in the car when I bought it....(bought the car in '99, with around 50,000 miles on it)
I now have more miles on that car than most people have on all their vehicles combined..............(currently 273,000)
I don't clean it very often (K&N actually recommends this), but I do look at it everytime I open the hood (It sits right on top of the radiator support)
It always looks dirty, however they say the dirt particles that stick to the oiled filter media help to trap more dirt particles..................so I leave it alone....

The engine is not worn-out..................It doesn't smoke or burn excessive oil..............I've never even had a valve-cover off the engine the whole time i have owned it...........
For a stock LT-1, it still runs strong, and I'd be willing to bet it has just as much horsepower as when it was new................maybe even a few extra  

The only thing that happens with these type of filters, is that some of the oil gets pulled off the filter, and gets ingested by the engine.......................Every once in a great while, I have had to clean the heater wires in my mass air flow sensor with a cotton swab, and some rubbing alcohol. The oil deposits on them, and leaves a film.........

I clean and re-oil the one in the FJ air-box once in a great while.(usually if I have to remove the airbox for some reason) Which is about once every 4 years or so........................Otherwise I leave it alone.

I am considering going with the UNI pods (only for the reasons that Noel stated) But I'm not sure if I want the extra intake noise?  
I'll have to decide that one down the road some time...............

For what its worth, when I cleaned out my UNI dual pods at the RPM shop during my last visit.... They were filthy, full of all kinds of dark dirt and grime. That covers about 6K miles of SoCal riding, not AZ sand and silt. So I know they filter, and I keep my off roading on the FJ to a minimum  , and I like the ease and access of not having an air box.

With the Uni Pods, what sort of jetting changes are you finding necessary ?

I also saw the Ram Air Pods on ebay..........

Interesting opinions. I've got K&N's uni filters in both my FJs. They seem to work ok. Both bikes have big mileages so I'm not going to change now. K&N recommend cleaning at 50,000 miles. This is far too much. I'm in Scotland and it's not dusty here but they needed cleaning at 15,000 miles. When I sprayed the filter with K&N cleaner and put them into water the dirt that came out was very fine - like smoke - so they must be stopping very small particles.

Noel, I must disagree with your statement above.  

Ed, I've just read your post several times over and from my reading of it, we are saying exactly the same thing. Nothing to disagree with.

Airborne contaminants wear your engine out.

The amount of that wear is relative to how good your filtration is.

Good filtering = minimal wear.
No filtering = lots of wear.

The only thing that could ever be disagreed about on this subject is what offers the best filtering.

None, I installed the ss screw/o ring kit in the carbs the same time as the filters so I had to retune the carbs anyway, but all the jets and needle heights are the same as before. Runs well with no flat spots and revs to redline strongly with that sweet induction sound.

One could surmise, that if a company sold such garbage it would have ceased to exist long ago. Either that, or the marketing and selling of its products is one of the biggest scams/swindles perpetrated on motoring enthusiasts and performance seekers for a long time running.

This is a great quote. 

First thing I thought of was Harley Davidson.  :-)

Bose and K&N are products that don't come close to equaling their advertising campaigns.

I feel the same way about this product...

OP: I installed a UNI air box style filter this past spring. I can't speak to any changes in performance. For the cost of paper filters around here it made $ sense to go with the re-usable foam for that reason alone. It was a bit messy to get saturated and drained of excess filter oil before installation, but no headaches. I was all set to go with UNI pods because before this I had my carbs in and out so many times, someone said I should mount them with velcro.

Once I got the carbs dialed in, I have had no cause to remove them so I'm good with the air box setup.

I`ve got a set of the dual uni`s on a recooperating FJ, ready to go, but untested yet. I too had concerns re the extra intake noise.

A few weeks ago I found myself in a 100klmhr speed zone doing 80klm/hr on the side car, behind a large truck. I went to overtake but was concerned at the distance of vision and the familiar missile just behind and in the overtaking lane, giving me a right of way. (Does he realise how wide I am?) I chose to let him have his head and backed off. Summarising the situation of my giving way and the diminishing vision of bitumen, the rider and new owner of my previously stock FJ passed safely, with the throat well and truly open. I immediately knew something was different with both the language, and my old girl`s delivery of it. I knew then, I wanted what he was having with her! (Basted....she was an innocent sweet thing!  )

Now I can`t wait for my own Uni concert.
