Man they really work...

I serviced another set of RPM Dual Pod Foam Air Filters today. It still amazes me just how much dirt come out of the filters. The carbs were spotless, but the dirt that came out of the filters is just amazing...

Ordered a set today.  I have a really old set of individual K&N pods on my FJ but the rubber where they seat on the carbs has become so deformed with age that they slip off from time to time.  I'm fixing that problem once and for all at a price 1/3rd that of a new set of K&Ns.  Thanks RPM!

When the pods are cleaned out and leave that behind, and the carbs still look clean, they are doing a great job. I have had this same experience every time since I went to the UNI pods. I just pulled my UNIs off for a clean, I will take a pick of the intake plenums of the carbs before I put the UNIs back on.

I was considering buying another set just so I could have a clean set ready to switch out each time I service them. Its nearing that time for me to get another RPM cart into the checkout isle anyway.

That is a great idea Mike!  

I wash mine, shake them out, then let them dry in the shade for a day, before I oil and reinstall them.
I like to be sure they are completely bone dry before I use the foam filter spray on them.

A second set of clean Uni's, stored in a zip lock Baggie, would come in very handy.

Here are my carb inlets after about 4K miles with the UNI pods. The pods were the normal grungy and cleaned out easy with hot water and dish soap.

A good way to check if a filter is doing its job, is to look at the needle.

It sits directly in the airstream and if it is rough/pitted, then your filter is not good.

That's my grit in Randy's sink in the OP. My inlets look just like the Monkey's. We did, however, fine a couple cracked manifolds and squished o-rings that were letting in unmetered air. She idles beautifully now, and no more riding the clutch to drop the idle at a stop. I was surprised to see the vigor that Randy used when cleaning the filters. I assumed they were more fragile than he showed me. It takes a good soapy squeeze on these filters to get the deep grime out of the folds. Don't be shy, they're very resilient if you don't rip them by pulling them along the seams.

Much has been written on the forum about the superior filtration of the pods and I use them myself but the crap that washes out of them is mostly stuff they pick up because they are exposed and sticky, not an indication of better filtering. They get covered in all sorts of rubbish that would never find it's way into an airbox and because they're oily and cellular, it sticks.

My judgement was based on the clean carb inlets, regardless of how much crud washes out. Clean carbs are the goal. Less crap getting sucked in. I am happy with my personal results on both my FJs. And as you rightly pointed out "it sticks", that is why they work so well. I don't venture off road with my FJ when I can help it, (I destroyed two header pipes in one event) but all the more reason to filter out as much as possible and keep the Kookaloo going.
