air intake pipe from k&n or airaid

Yes cobra head matched with TB opening.
You need the shortest radius 90 you can find, and that seems to be it.

Headers (exhaust system to 3” outlet pipes), high lift cams by TODA Japan (same with the 1UZ), ported intake and exhaust heads) plus strong valve springs will definitely give you additional HP if you’re going the Naturally Aspirated route.

Yeah I’ve never actually considered anything like this for my LC. You think I would have considering the amount of power gains you can make on an LS1 (which I have in my other 20 year old car my wife hates) with bolt ons. I’ll have to do some research.

$59 Tundra intake from eBay, $11 Tundra valve cover vent tube, one vacuum tee, and some silicone vac hose I had in the garage. Beats $475 for new LC intake tube to replace the one that broke!

Is that pipe with vacuum fittings custom?

 

[jerryb]

yes, drilled three holes for power steering vac, fpr vac and passenger side pcv supply. match up mm for inch barb fittings, plastic is fine. silicone hoses for fpr and power steering valve. @oakback

I recently installed the airaid tundra kit. It takes 10 minutes tops. There is nothing janky about it and it fits the space between stock air box and throttle body perfectly. The directions on hose routing that come with it match up to my 98 lc. It is slightly louder, granted I have a DS exhaust manifold leak and no resonator from a recent bumper install. This kit comes with a reusable dry filter, I popped it in and it fits, old filter needed to be changed any way. Not sure if I’ll use this “reusable” filter long term. I’ll try to post a video clip a little bit later on.

Looks good. Thanks for posting these.

I recently installed the Airaid (K&N) intake tube from the Land Cruiser/LX470 kit that is now out of production from what I was told. However the parts can still be ordered directly from Airaid (K&N). Those PNs are; "Intake Tube - AIR-KIT981T", "Rubber hose connector - AIR-KITHUMPHS11EPDM", and "Reducer hose connector - AIR-KITRDCR04". All told it was about $120 for the parts. I used the OEM Factory intake tube clamps for the install.

The Airaid tube only has 2 vacuum ports; one for the PS valve cover hose, and one that has a tapped hole that accommodates a 1/8” pipe thread. I picked up a black poly hose barb that accepted a 1/4” dia. hose thread. All three of the factory lines are there just to get vacuum and the y-fitting works and makes no difference.

One thing I will be doing is trimming about 1/2” off the air filter housing side of the new intake tube. It’s a touch to long and limits some the flex in the rubber connector.

Overall it was an easy install and aside from being a little more throaty during acceleration, it wasn't very noticeable. I made this change to make the engine more accesable and it cleans the engine bay up some. Just my $0.02.

Found this while reading about canister filters on the 100-series.

Why does the 100 have such a convoluted intake pipe? Is it to reduce noise while maintaining flow?

People think it is just for sound reduction but it's not. Search Heimholtz. Do you think the power LT6 motor cares about intake sound reduction?

To be fair, this is a different application of the same physics. Yoshi's implementation is 100% for intake drone reduction.

I'm sorry if I confused anyone. Herman Helmholtz, born in 1821, did not design your Toyota air intake system for power.

Yes! Ditch all that extra intake plastic. Adding to my wish list.

Mine works sweet. The engine sounds like a V8 should under throttle. Just like any vacuum cleaner will demonstrate, does anyone still have one? When the intake hole is less restricted, the motor runs freely. Air In - Air Out Grasshopper!

I ordered this to try out. It's a flexible silicone intake hose that you trim to size. I'm worried it might collapse under WOT but I'm going to test that out. Might be worth it if I can make it work with the stock airbox.

You install this kit?

I have and it's decent, no collapsing under WOT, very thick silicone, the vacuum lines supplied with the kit are pretty much useless and didn't look or seal great so I ended up making my own. Overall not a bad pipe, it's been on my truck for about 2 months now with no issues to note.
