No modding done to the airbox.
You take a stock paper filter, cut it up so that you only have the plastic neck (base) left. You should be able to break/crack the epoxy to get it off of the plastic neck. Also keep the filter endcap, again breaking the epoxy off of that.
Using a hose clamp, attach a K&N RU-2820 filter to the OEM filter neck. It will be a tight fit, and will be easier if you use a hairdryer to heat up the K&N filter's flange to make it more flexible.
Finally use some small screws to attach the endcap to the end of the K&N filter.
End product should be like this:
And before anybody says anything about the K&N drop-in, this here costs less than half the price of the K&N drop-in, and it actually fits BETTER. This fits 100% like stock, whereas the drop-in replacement filter doesn't have the endcap like the stock filter, nor does it have the rubber gasket around the neck that forms a seal when you put the airbox lid back on.

I'm still using this same filter after 3 years and well over 80K miles.

No it is not better than a CAI or a SRI...people put after market intakes for 2 reasons...better flowing filter...and faster, smoother air flow. The K&N filter takes care of the later and the smooth tubular piping speeds and smooths air flow. The stock intake arm is a good design but almost any intake will beat it.

Re: (9000rpms)
The air only travels as fast as the force sucking it in, and totally free flow will put a negatice effect on HP. For example, if you take a vacuum and replace the pipe with another one much larger in diameter, you will see that even if you were to put it on a pile of dirt, none would be sucked up. You get teh same thing usin ga DIY intake, for 1/4 of the cost.People put aftermarket intakes on their cars because they never thought of the idea to make their own, or theyre lazy/ricey.

Pat, you're always good for a discussion
I've been theorizing that this filter might acutally perform better than the bigger one... povided that one puts the stock cover back ON.
http://www.derestricted.net/it...x.htm
The reason for my theory is that if one were to put the stock box top back on, with the larger filter, there is little space surrounding the filter itself, therefore more restriction with the filter. But with the smaller filter, there will be much more open room for the air to freely move about, which in turn makes for a better flowing system...
Whats your ideas on this?
To reiterate, your set up is better if the box top is left off (as you have done) but if one was to close the box top, the smaller filter will offer better performance benefits.

with the top on and a smaller filter.. wouldn't it be like drinking from a smaller diameter straw vs. a larger one? i know there will be more open space in the box when the filter is smaller, but when the engine gets going, there will be a vacuum and all the air from the inside of the box will be gone and so it will have to be drawing air from the lower piping... in the end, you'll still be sucking from a smaller straw with a smaller filter.

haha did you read what I posted? The K&N drop-in costs over twice as much as the RU-2820 filter and doesn't fit as well as stock.
I do not leave the lid off my airbox, it is in place at all times. I had it off in that pic when I was replacing my radiator and thermostat (I had removed the intake to get to the thermo housing).
I also pulled out all that resonator junk below the airbox, and replaced it with a PVC tube running down behind my turn signal, a.k.a. DIY Icebox.
I drove my car once with the lid on, but nothing below the airbox, and it was quite loud. Just putting that piece of tube in there made it alot quieter, although it's still just a touch louder than with the stock resonator.

Re: how to mod a k&n into stock airbox (PatrickGSR94)
I don't have the same filter you have. As a matter of fact I think I have the "drop-in" which doesn't quite fit. . . but I made it fit with no modification.
When I purchased that "drop-in" K&N filter, I also bought the two rubbers seals from Honda so the filter would tightly rest inside the box once the lid was on. I also managed to get a hold of a used Integra R resonator too as I didn't want to use the GSR resonator. The inlet is in a different positioned differently and so, it draws in air from outside the engine bay unlike the resonator of the GSR that draws air from the engine bay.
I'm glad I returned my intake back to stock. I was tired of AEM's CAI.

Re: how to mod a k&n into stock airbox (Rebel Scum)
I've got the K&N 3130 filter, which is a little smaller & tapered. There's more room for air to flow around the outside of the filter. But there's probably no real measurable difference vs. the one Pat's got.

yeah see what gets me is why couldn't K&N just make one with an OEM-style filter neck w/ the rubber seal and everything? I mean come on, they didn't even come out w/ their 94-01 Integra drop-in filter until 2001 I believe, right at the very end of the G3's 8-year model run. It's not like they didn't have the time to do the R&D, and then they end up charging out the @$$ for it.
