Monsterflow and K&N filters for $30!
We have a bunch of 3" Monsterflow and K&N air filters we'd like to sell. All are priced at $30. Its hard to imagine finding these at a lower price anywhere, The Monsterflows list for $99, the K&Ns for $49 and AEM bypass valves for $50. We got all this stuff when we recently bought out Place Racing's CAI inventory (also on sale, and now orders are dependably filled from our warehouse).
The Monsterflow filters are the same as the ones used in Place Racing and Cattman CAIs; the K&Ns also are the type that are compatable with CAIs (cylinder-shaped). I'm partial to the Monsterflow because it uses a silicone, rather then oil-based filtration agent, but both are great filters.
Either of these quality intakes can be mounted directly to the MAF with an MAF adapter to make a simple but very effective intake for $55. [We have MAF adapters in stock ($25) for 00-03 Maximas, and will have more 89-99 adapters soon.] As an MAF-mounted filter, I recommend the Monsterflow because they have a velocity stack built into the base to eliminate a lot of the air turbulence (same as the JWT POP intake). The K&N filters work better on long-tube systems that distance them from the MAF.
To replace the entire stock intake apparatus, we also sell the upper tubes in black and silver to go between the throttle body and MAF, complete with cool black clamps and connecting hoses - we have these for most Maximas at $85-90.
Of course these can also be used as replacement filters for CAIs, and at these prices why bother cleaning the old one? We do not recommend cleaning and remounting any oil-based cotton filter (like the K&N) on 2000 or later Maximas due to the increased sensitivity of the MAF hotwire to dust and carbonization.
Finally we have the AEM bypass valves at a great price ($30). For those concerned about sucking up water through a long tube intake, these should provide peace of mind - regularly $50, now $30!
You can order these parts by phone from the Cattman offices (520.730.9309, 9-6 Pacific Time, M-F – sales and tech support).

All questions based on a 5.5 gen
Does any of this translate into a better price for your complete CAI?
As I still have stock intake, for $55 I can have a basic WAI or for $85 have a little 'bling' with my WAI?
EDIT:********
PLease ignore my above. After posting I saw the thread on the complete CAI for $135 and have now purchased the yellow unit for my '02.

Well, if you take my comment above seriously, you will install a Monsterflow rather than a K&N if you want to mount it directly to the inlet of the MAF. The K&N has no velocity stack built into the base like the Monsterflow does, and as a result, the air coming across the hotwire in the MAF is much more turbulant - this is not a good thing. It "confuses" the MAF and ECU because the signals from the hotwire are flipping back and forth constantly. We've tried either type on the dyno, it really does make a different.
I'll just come out and say it, for the reasons I state above its NEVER a good idea to mount a plain filter directly to the MAF - the only filters I can recommend for use this way are the JWT POP filter, the Monsterflow or any other filter that has a decent velocity stack built into the base.
Note its a different matter when a K&N or similar filter is mounted to a long tube intake (like a Place Racing CAI or any of the others with a long tube between the filter and MAF) because the air turbulance stabilized as it goes down the tube (once the length of the tube is at least 5x the diameter, you'll have fairly stable airflow, so the turbulance from the filter is irrelevant).
Anyway, back to the essence of your question. All you need to complete a basic intake )in addition to the Monsterflow or K&N filter) is an MAF adapter, which bolts to the face of the MAF, and then the filter base slips over its 3" opening and you clamp it on.
Easy enough for any noob. Only challenge is taking out the stock system without breaking off plastic bits (be careful with the stock parts you take out, treat them carefully and keep track of the pieces, odds are good that you'll want to put it back in the car when you sell it).

I'm not real fond of PayPal, but yes, we do have an account. It still routes with my private email address, so I'll send that to you by PM.
You might want to check with me to make sure you've got the right total amount, including shipping, before you send payment.

Either filter will attach to a 3" tube. The only possible conflict would be clearance for the filter itself, wherever it ends up at the end of your Injen tube. The K&N is a cylindrical shape, pretty narrow, so I can't see it being an issue. The Monsterflow is relatively compact, about 6-7" diameter at the base, so if you've got room around the filter on there now it shouldn't be an issue.

We sure do (read original post), they're $25 and the Monsterflow is $30 - a pretty good intake for only $55.
If you want to take it up a step, add one of our upper tubes (black or silver) to replace all the stock intake parts between the throttle body and MAF. We don't have upper tubes for all Maxima years, but we do for your 97. Total price would be $135 (some might say this is like the Berk intake, except that we developed it a few years before they did).
If there's a PR group deal CAI available, that's a better deal since you have the option of going underhood or CAI, but we're out of those for your car.

As long as the Berk includes some kind of MAF adapter with a simple 3" inlet, either filter will clamp over that. Again, I'd suggest using the Monsterflow in an intake setup that places it near the MAF.

They are the filters that PR used to use in their CAIs.

Well, given that the Berk appears to be exactly like ours (ah, innovation, don't you love it?), the Monsterflow should fit just fine.

Our out-of-date website isn't good for much, but there are actually pictures that should illustrate this for you - one shows the Cattman Monsterflow-based COMBO intake: http://cattman.com/img/prod/dsc_0411lo-rez%20cai.jpg
The filter is mounted to the 3" neck of the MAF adapter, which appears as a black flange bolted to the MAF adapter in that picture. I will point out that the ones we have now are silver. We still have the very cool black clamps.
If you want a close-up of the 95-99 and 00-03 MAF adapters, look here (noting that they are silver rather than black): http://cattman.com/img/prod/dsc_0393...%20adapter.jpg

So, I am correct by assuming that the Monsterflow is made of foam?

Its a one-size-fits-all sort of deal, so sure, we have a K&N for your car for $30 + shipping. We'll be happy to sell you either, but I think you'll get better results from the Monsterflow - a little more power due to less air turbulance and and a little less risk of that sensitive MAF going south because it doesn't use an oil-based filter medium.

K&N filters, on the other hand, use cotton gauze that offers one of the best filtration and air flow capabilities for performance intake systems.

Despite the certainty of your opinion, I'm afraid your knowledge is incomplete. There are a number of formulations and even different fabrication processes that produce what could be generally referred to as "foam". I don't think its possible to determine exactly what materials have been used from a picture, so I'm not sure how you can say that because the Monsterflow looks like "foam" then it is subject to the same shortcomings you attribute to the other brands.
I've heard of bad foam filters too, but the pliable two-stage material that Monsterflow uses in their filters has nothing to do with the more rigid material in the filters you're referring to. There is no pattern of disintegration with the Monsterflow.
In addition to being particularly popular with the Miata crowd for some reason, the Monsterflow filters have been used in thousands of Place Racing CAIs for Nissans and Hondas over the last four years. We've sold hundreds of Cattman CAIs w/ Monsterflows over the same period, and there is no pattern filter media breakdown or MAF failure reported on the forum, none by Cattman customers, none through Place Racing (I know the owner), none through the companies I know that sell them to Mazda owners. [I had one customer say his disintegrated, but that was only after a Nitrous backfire through the intake cooked the filter. ]
K&Ns are pretty good filters when new, but although they don't flow as well as the Monsterflow, that's not why Place Racing and Cattman switched to the Monsterflow 4 years ago. We dumped the K&N due to patterns we saw firsthand of MAF failures due to volatilization of the oil-based spray when its used to "activate" the filter medium after cleaning. This was even happening to the pre-2000 Maxima MAFs that were a lot more bullitproof.
I should be clear that although I could be wrong, I don't think that this problem occurs much, if any, with new K&N filters, because they come (I assume) with exactly the right amount of oil sprayed evenly over the entire filter. They're not a bad choice if you're willing to throw them away the first time they get dirty. [Except they should never be used without a velocity stack (like the JWT POP intake base) if they're within 15" of the MAF.] At $30/each, I know I'd never clean the K&N, I'd toss it out.
The MAF problems are associated with contamination and the cases we saw came up most often after the filter was cleaned the first time and the oil re-applied. Nobody ever gets the oil on evenly, and most tend to overapply. This causes excessive volatilization and the hydrocarbon molecules in the airstream carbonize on the hotwire, building up an insulating layer and eventually ruining the unit. That's the first form of MAF-trashing contamination that I associate with oiled-cotton filters (there are many, the K&N is one).
The second potential problem with the K&N's oiled cotton filter element is that it can easily be disturbed during cleaning. From my experience its difficult not too move it around at least a little, and some will stretch it a lot as they backflush with air, water, etc. That enlarges the air passages, and thins the material; filtration becomes uneven and particle pass through it that wouldn't have when the cotton material was in its original condition. Particulate contamination seems to be the #1 source of MAF failure in the 00+ MAFs and anything that opens up gaps in the filter will increase this problem.
I think the only reason that the Monsterflow is not better known (and, as a result, better regarded) is that the company that owns the patents and fabricates them has never marketed them effectively.

The Monsterflow's are capable of being rinsed in water correct? If so, i'll be ordering one today..
