Don't bother drilling, just try to "pull" it out with a putty knife. A couple of the plastic nipples will shear when you try to take it out.
I did this ages ago and have been getting 20-21 MPG from the trip computer when I commute in So Cal Traffic (slow & go). That translates to 18-19 MPG via the real world odometer readings, traffic and some city driving. I thnk there's more difference between 3/4 and full throttle... kind of hard to explain. Also, I got in the habit of turning off the a/c whenever I get in the truck.
Now I'll wait for the same response telling me how I have no proof that removing the filter improves gas mileage or power... Toyota engineers are all knowing, and how I kill four thousand infants with the additional polution I contribute to the enviornment.

The problem is not with one or two people removing smog control devices. It has to do with clean air requirements. In my field, CARB requires, we install special valves in VOC service. This used to be limited to lethal services only. (For example...something that might cost $100 bucks easily costs $1000+ for a 1" valve) If it is just one person (or one valve) it isn't that big of an issue. But when you multiply that over 10,000 4runners (or piping connections,) the fugitive emissions add up FAST! Fortunately or Unfortunately (depending how you want to see it) it is a part of the system we have. There doesn't seem to be much you can do about it anymore unless you own a vehicle older than 1978/79 (something like that) you don't have to worry about anything and you can pollute to your hearts content!

I did see the Sequoia, very cool

Hey thanks!
Just did this mod to the sequoia as well Once again it seems to have stepped up the throttle response (not that it really needed it ) but it also made it so I can actually hear the engine. Now to get an exhaust put on to wake up the neighbors.

Looking back, and exacto knife around the edge of the filter media would work too.
Just leave in the filter frame.
It appears that at 4000 to the redline is more responsive.
Seems to be a bit more air intake sound at WOT.
This may have provided a couple of ponies above 4500.
Less restriction is a good thing. Good mod. Do it gang.
I wonder if this reduces the converter smell for those who have it?

I am guessing this would void your emissions warranty if the dealership bothered to check. Not that I am one to judge. I put a CAI on my 04 @ 20k miles. I have almost 90k now and have never had a problem passing North Carolinas yearly emissions/Safety check. I do have a CARB sticker under the hood for mine.
K&N's kits did have a C.A.R.B. approval at one time, but I think they pulled it back since you can not find a 57 series (FIPK) kit on there web site anymore for the 4th gen 4Runners. The 63 series kit (Aircharger) are not 50 state emissions legal like the 57 series usually are.

I am sure you're right.
The good news for the V6 is that it's listed as a separate part for around $35. So if V6 4Runner showed up at the dealer minor evidence of tampering is explainable... "Oh I changed it and couldn't get the little buttons to work right that's why it looks like it was messed with... " Not that that makes it right.

we've been debating about these things for years here. Do a search and I'm sure you'll find several threads, at least two of which I have taken part in. I think the general consensus is that we aren't sure removing it does anything, either good or bad. I haven't taken mine out, even though I've had it open and looked at it several times. I think someone talked about taking an air compressor to it and noticing that it blocked the airflow significantly. I'd love to see a dyno on this. Two before, and two after. Still not sure if I'll take it out.

I took mine out a couple of days ago.
1) It's only been two days but the onboard lie-o-meter has settled at 1.4mpg higher than it was.
2) As previously reported; riding with the back window down is MUCH better. It is not perfect, it can't be without installing a side exit exhaust but it's way better in terms of sulfur and ammonia smell. Why? No clue...
Thanks LV4R

No probs! Believe it or not I actually have the sulfur smell with the Sequoia too. It's not as bad as the 4r though thankfully.

Just did this. The computer recognized an immediate improvement. The range went from 253 to 276 immediately (3/4ths). I then proceeded to fill up the tank. Range was 394! Woo! I just filled up Friday and the range was 352!
Can't really tell MPG until next week.
Was getting 16 MPG.

For those decide to try to experience... Please use the old school away to check your mileage meaning filling up the gas tank at the same gas station (at the same station twice), write down the mileage...
This would be a more accurate way of checking the gas mileage otherwise it could be that the sensor is confused. I don't know how Toyota do it exactly but it's only a rough estimate and my guess is that any mod to the engine would require the sensor to be recalibrate.

The onboard does give a quick, accurate indication of the trend based on my experience.
The old school way reveals an average of .8mpg better over quite a while now. The onboard has settled down to indicate an average of .9-1.0 better. Once again the onboard shows 10-15% optimistic.
