LC100 cold air intake (1 Viewer)

[Mike NXP]

The idea of cool air intake itself is incorrect as the engine is warmer than outside.

I never settle for anything other than OEM parts (or do it twice). Those oil filled filters will clog all pores within a matter of days if you drive on a dirt roads, then the engine receives less air. Oil can contaminate the MAF sensor too.

Well the first part of this is not accurate. Cold air contains more oxygen and will combust better and that's a fact but it's just not necessary on this particular engine.

Agreed on second part of that statement.

It's a cruiser people, keep it OEM and stop making it less of a land cruiser.

Why change what has worked very well, for billions of miles "Collectively speaking". Which is the factory design! The exception being a snorkeler.

Personally, I do not like seeing any of these after-market cool air system on the 100 series 4.7L. For that matter, even the filters that claim additional HP gain. Which allow more air into intake manifold, at shake of filtration. Which is not good for health of cylinder walls and rings. OEM filter is best deal IMHO.

I've one in shop today. Fuel trimsView attachment 3180964 will not come inline. Why? WTFK, as it's gone down this rabbit hole!

Another thing I see in some with some open air filter design. The filters get water-logged, starving intake of air in the rain.

Might be related to whatever is going on with the electrical tape on the MAF electrical connector and the tubing going to the soda bottle?! Looks pretty crappy!

Very likely.

Soda bottle, is just a catch for AT return line fluid from PS reservoir, I just flushed. I've the PS reservoir in my sonic cleaner, as I replace the rack & pinion and PS hoses.

But why, what do you expect to accomplish? The 2UZ pulls air from way back inside the fender, it's not like it's pulling hot engine bay air in. You will have no note worthy performance gains and you will most likely take a really good air filtration system and make it worse.

If you want less dust ingestion then a snorkel make sense but even that seems like a waste. I drive in constant dust clouds all summer long up here and I have no issues with stock filter setup.

Because a stock air intake was not available at the same price and it cleans up the engine bay.

Was referring to the person who started this thread not your comments. Then I realized he's in Dubai and might have legitimate reasons for wanting a different style intake.

Is getting rid of the stock air resonator part of the intake worth it? Apparently, the air resonate reduces harmonic pressure and increases horsepower. Interestingly this is worth around 5 hp (no joke). Breathing Fresh Air – Intake R&D, Part 8: Final Design - https://www.mishimoto.com/engineering/2019/10/jeep-wrangler-intake-2018-rd-pt8/

Just got done working a similar issue on our C7 Corvette. A supposedly "drop-in" no-tune air filter from a popular vendor was causing the LTFT to go 15% positive all the time. The MAF on the Vette is close to the filter, like an LC. The MAF didn't like the extra air flow and was dumping in fuel to adjust for what it thought was a lean condition. Put a stock air box and filter back in and I'm betting it will be fine.

I really wish I could just buy this air box piece somewhere, the one I am pointing at in the attached pic. I almost considered a modification to the factory system, until I started reading here. I myself prefer things to be OEM as much as possible.

I've JB welded, glued, fixe and re-fixed this stupid little pipe I don't know how many times. This last fix seems to be working the best, but it's an eyesore. I've heard of and saw people do plastic welding, but that means to me I'm buying a tool I'm going to use one time.

hmm.. why not I just buy this piece I'm pointing at in the picture and call it a day. I almost found it used, but then the guy on the world market stopped talking to me. I'm still in search, oh yeah, and I don't want to pay 200 bucks for one on eBay or anywhere else. I'd be happy to pay 40 dollars for that piece.

If you want the piece you are pointing at, you have to source the entire factory intake tube, which is what you are pointing to, I suggest checking ebay (which is more than you would like to spend), various Facebook 100 Series Land Cruiser groups ("UZJ100" and "Land Cruiser Lexus LX470 100 series USA") and Facebook LC sales groups ("Toyota Land Cruiser Classifieds", "Land Cruiser 100/LX470 UZJ100for sale"), Facebook marketplace, and of course ih8mud Classifieds. Maybe a local pick and pull yard might have one (copart)?

Unfortunately, I don't think you will find one for as cheap as you would like.

I have not seen a Land Cruiser in a junk yard for a very long time. I do periodically check though. I'll be waiting this one out before I spend the honkin 200 or so. FB aka world market, I've been searching, and every time I get a bite, it's sorry Charlie. oh well. that's life. I'll keep searching.

I believe @87warrior is successfully running a Tundra version which are both easier to find used and less expensive

Yep! The big baffle/air chamber cracked on my original 100 series intake pipe. I replaced it with a 4.7L Tundra/Sequoia intake pipe. I installed this over 4 years ago, but do remember needing to extend the fuel pressure regulator vacuum line and the power steering vacuum switch lines needed repositioned.

I haven't seen this . Some folks have done some aftermarket air intake setups but in my opinion it's useless and the 2UZ doesn't see much benefits from changing the OEM design

Thank you for the reply! What about using something like this (link below) to replace the stock throttle body -> stock airbox tubing and leaving the stock airbox?

https://www.amazon.com/gp/product/B0026K2MO4/ref=ox_sc_saved_title_8?smid=ATVPDKIKX0DER&psc=1

Or is it best to leave it in stock?

Also, what are your thoughts on supercharging the 4.7L if I have a 100 Series Land Cruiser (2000) with ~190k miles?

Thanks again!

Totally depends on your opinions on the matter, I think each persons will vary.

For me, my 100 series acts as a ultra reliable back county hauler and I don't stray from the OEM build on this ever.... I know some people super charge them and I bet its bad ass but it really depends on what your end goal is.

I think if you add the super charger I'd also want to add the part time 4wd kit so I can rip around in RWD and kick up some dirt.

Snorkel may help in regards to air filtration but even then my OEM filter does fine even in extreme desert dust.

Thanks for the info! Do you have a link to a part-time 4WD kit that you have heard good things about by chance or a brand/model number?

Thanks again!

 

[Mike NXP]

@cruiseroutfit is the go-to for the part time kit. They might even be able to tell you some pros/cons of modifying the 2uz with a super charger. I believe overseas and some tundras have the 2UZ with a supercharger ??

Does this kit positively affect MPG on a stock drivetrain setup by much?
