Are 2.7L air intake boxes the same as the 2.4L?

I am looking for a used air intake box for my 2001 tacoma 4-cyl (2.7L) 4x4. Are 2.7L air intake boxes the same as the 2.4L 2WD? I'm trying to expand my search because I'm not having any luck. Also, what model year ranges are compatible? Is it 1996 to current? Thanks.

2.7/2.4L air intake box for '01 tacoma

Thanks for the reply! Good, I thought that they were the same. What about year model compatibility, though? I just have a "deckplate" mod planned for it, and I am scared to chop up my existing one. My plan is based on an idea from that customtacos.com site. http://www.customtacos.com/tech/arti...4/intakepart1/ Thanks again for the reply! Ed

I am assuming they are all the same because in the link you posted that tacoma is a 95 and it has the same airbox. and if you think about it, you only need the bottom half of the box, so that may make it cheaper if you can find a junker just selling the bottom, where are you looking to buy the box from? I might be buying one also, i have smog coming up in a month and I have heard of smog stations failing people on the visual because of modified airbox.

I have been searching on the internet. Basically any website I can find. I have also checked my local junkyards. I have been just asking for the bottom half, like you said. I didn't catch the '95 on the custom tacos link, so maybe I have even wider search options. Also, I didn't think of searching for forerunners. If I find one, I'll do a little write-up here and maybe get some noteriety. haha.

Re: Are 2.7L air intake boxes the same as the 2.4L?

bump, and I was hoping for some more advice. I found a used bottom portion of the air box I'm looking for for $25, but the shipping is another $15, so $40 total. Am I sinking too much money into the deckplate mod for a 4-banger that will likely just provide more psychological horsepower anyway? Thanks.

any last minute advice before I do this? I am thinking of buying the $40 airbox, just for peace of mind. I guess I'm just hoping someone will chime in and either say "#%@# yeah! it is totally worth it!" Or "@#$% no, it doesn't do anything." Anyone??
Thanks.

I would have paid $75 for the deckplate mod on my 4Runner. Granted it only costed me $20. Of course, I have the 3.4, but I dont see why it wouldnt help the 2.7 just as much.

Awesome mod, well worth it.

the only reason i havent done the deckplate mod on my 2.7 is because you cant do it effectively on the front of the air box because it is not flat nor big enough to fit a 4" deckplate there. the only possibility is to do it on the side where the engine is, now i would assume that since that is where you will be getting the most warm air, i cant imagine how the deckplate mod would work any better than just removing the elbow. but thats just my $.02 someone let me know if i am wrong, i would like to actually do it if it works!

I think that's a good point about the 2.7. I just like the sound of the deckplate vs. the elbow.

Good point about the warm air. Do you have your elbow removed? I have come up with a PVC-pipe idea that basically follows the mod at http://www.customtacos.com/tech/arti.../intakepart1/. I think you can go wider diameter than 3", but I haven't actually measured how big you can go. I think 4"? The PVC pipe I was thinking of isn't a full 90 degree bend, but a partial bend. The 4" tube is much wider so there wasn't as much room for the 90 degree bend. But like you said, it is out of the engine-side of the airbox. There is space there for all kinds of air flow when the truck is moving, so maybe the air wouldn't be as hot?? The airbox I was going to buy was for the 3.4L after all, so I'm back to deciding whether or not hack up my own airbox. I'll keep pondering......thanks for replying! Ed

the PVC pipe idea is pretty cool, but i just dont know how that would work very well either...
it seems to me it is just like having the elbow on the other side of the box. now most people remove the elbow because all the bends in it are too restrictive, so this "new elbow" seems like it will suffer from the same problem, i think the bend in it will not allow for a sufficient amount of air to flow in that would create any more HP. just seems like a new elbow that is almost as restrictive. but like i said before, i'd like to be proven wrong, so that i can do it

will the airbox from the 3.4 fit on the end of the MAF sensor and the intake piping? are they the same distance so they will fit up perfectly? if so that would be great, then we could have a really nice deck plate mod to do on this sucker

swapping airboxes

I don't know if they 3.4L and 2.7L are interchangeable. I assumed that they were different because, well.....they bothered to make them different! But I have no idea. My buddy just bought a brand new 3.4L TRD Tacoma and after test driving it I was overcome with jealousy...... My only comeback to him about his superior power was, "I can get 24 mpg." But maybe I can do some checking and comparing with his versus mine. If I did want to swap, I'd have to buy a 3.4L airbox and a new high-flow filter, so I'd be back to the same problem of spending quite a bit of money for what a lot of people are saying is psychological horsepower gains. Your logic about the elbow makes sense, too. My idea with a smaller bend in the PVC pipe would address that, but the air would still have to make a 90 turn to go from the cut intake to the filter. Thanks for the reply! Ed

Just to clear things up...the deckplate mod on the 3.4 is not psychological. It is good for at least 5HP to the wheels. Not sure if that's what you meant...you were probably referring to the 2.7.

If so, then

My comment about psychological power gain is just my own conclusion based on what other's have told me. Some people seem to really like their deckplate mod and say they can feel it. While I've heard from others that say they really couldn't feel a difference, but it sure sounded cooler. These are on the 3.4's. My opinion is that I've got a 4-banger, so anything I can do to squeeze more power is probably worth it!! I want to try some intake ideas, but the 2.7L box just doesn't seem to lend itself well to any really good ones. But I guess that's what this collection of toyota knowledge is for!

From Gadget's site, in 1st, 2nd, and 3rd respectively:

Run 9 Stock Box No Front 173.3 HP 205.5 HP 208.6 HP

Run 7 Stock Box 168.8 HP 199.5 HP 202.2 HP

Run 6 K&N FIPK 169.4 HP 202.3 HP 199.0 HP

You be the judge.

Here is the link to the data.

That's cool, it is nice to see the data on that guy's page (I'm an engineer, I love numbers hahha). So it seems that putting the new intake for the 2.7L on the side rather than in front wouldn't result in any less gain, according to Gadget finding the elbow removal being nearly the same as the front deckplate. But what do you think of the previous reply on this thread about the hot air since the only accessible part of the air box is facing the engine? Do you think it would be an issue?

PS - I think it is a little amusing that the FIPK is outperformed by the stock box with minor (<$20) mods. It inspires the do-it-yourselfer.

Yeah, I like data too (QC here). Anyway, I think the hot air could pose a problem on the 2.7. However, you mentioned the 3.4L HP gain being psychological, therefore I (Gadget's info) defended it. Now, if I had the 2.7, I would do the elbow mod, as others have mentioned. On my 3.4, I have gone one step further and placed hot air blocker between the airbox and the radiator/fan area. Not sure how much that helped, dang air is so hot here in PHX as it is.
Anyway, keep us posted on what you do.
