As far as I can make out this is a filter which removes oil from airflow which is fed back into the turbo of a diesel - a Google will give a better explanation that I.
I am inherently sceptical of this type of add-on as, I know, motor manufacturers go to significant lengths to ensure their products are as capable as possible/reasonable.
Nevertheless; a catch can filter would probably add $25+ at OEM level and that is a lot of cash so it may be they decided their engine would do x-km without a catch can and x+y-km with one and the difference wasn't worth it to them... but it may be to me.
Any thoughts people?

Well i have a 2005 diesel hilux, no catch can , the vehicle has no issues.

Have a google search for images of blocked EGR and make the decision for yourself , a no brainer for me . manufacturers plumbing the engine fumes back into the intake has nothing to do with good performance or longevity it is purely to satisfy pollution control requirements . fit a catch can and drain of the crap yourself at each service , usually around 30-40 mil although our sons new hilux is producing between 75 and 100mil every 10,000 km .
Or let it recirculate through the engine and risk having to strip the inlet manifolds at around 100,000 km to chisel the baked on crap out at the same time you will probably have to remove the inter cooler too to flush that out as well because the oil settle in that as well .
someone will be along in a minute to tell use catch cans are just a con to rip us off so no more input from me .
just stop and do you really want to be feeding that crap into your inter cooler ,through your turbo, the the EGR and the inlets to finally be burned in the engine ... OR fit a catch can and simple open the tap and drain it off at each service .

Just to add people are reporting around $1000 to $1500 to remove ,clean and refit the inlets depending on the vehicle .

I second Outlaw40's comment about cleaning inlet manifolds. The recycled oil fumes get mixed with the exhaust gas recirculation system and burnt in the engine. This is fine in theory, but a lot of the oil gets burnt in the intake manifold as well and this causes a buildup of gunk. A simple means of preventing this is to prevent the Exhaust Gas Recycling (EGR) valve from opening. This can be done by a simple resistor in the control circuit or by blanking plates which physically block the exhaust gas from entering the intake manifold. Since EGR is required for pollution reasons, both of these measures are illegal but are commonly used out there. Of course, oil fumes are still recycled back through the turbo and intercooler even without EGR, but they are burnt in the engine anyway. Oil fumes can condense in the intercooler and partially block the airflow through it. Catch cans remove most of the fumes and therefore intake manifold and intercooler blockages.

Agree with ol40, however suggest that you mount the CC in a place that is not above the exhaust and is Checked/Changed Every Service, as when the filter is blocked/CC full, most have a release valve on the top and with some units oil/fumes can drip down the side of the CC on to......

catch can is money well spent not only does it stop the inlet manifold from blocking it also keeps the boost sensor clean and operating to keep your fuel air mixture at the correct ratios, some engines have a lot more blow by than others my 2.8 liter jeep caught about 100 mm between oil changes where as my current car 3.2 liter ranger collects next to nothing

We fitted one to our 200 at 70k wish had done it earlier , I drain it roughly every 10k and theres always a cup of oil in the line , mine has a hose off the bottom down to the bash plate so i drain it there. Most oil in it was after a bit over 3 mths in tassie . i think it probably accumulates less on long straight hauls .

Wouldn't be without one. I've seen no. 4 inlets almost blocked. Head had to be removed. Ryco are now doing vehicle specific kits. No idea of prices. Should make it easy for the D.Y.I.er.

hi Ranger 3.0ltr Recently have done a manifold clean with inlet pipe/ intercooler /throttle body /egr / sensor /cylinder head ports , cleaned at 100,000km. Approx 3-4mm build up . Throttle response and fuel economy slightly better EGR by passed previously Fitted Ryco catch can
Labour clean ALL INLET 8 hrs ,,parts less than 100$
CHEMICAL CLEAN DID NOT WORK. This was done 2000--3000km prior and I used 2 cans sprayed into manifold . Although it might have softened the sludge for easier cleaning .
The Europeans re VW ,BMW have been cleaning inlets for a long while and specifically been walnut or soda blasting the inlet ports . Look into U Tube .
Hilux D4D are just as bad as others .
Some cars /trucks have factory fitted catch cans !!!!! WOW . The catch can filters are changed every 30,000km and made by Ryco .

New Landcruiser 200, around mid 2019 specifically are Not recommended, some running change by Toyota.

The manufacturers will say not required! As it could be said they ARE admitting there is an issue ! Had the same with work utes rear suspension bushes.

Not required and not beneficial are 2 different things . manufacturers dont want your new vehicle to last past the warranty period .

Hi Not suitable not recommended ,MORE MAKETING bull**** ,,=catch can or sealed for life transmissions LOL LOL
UNLESS Toyota HAVE COME UP WITH magical PISTON RINGS THAT 100% SEAL . Not gunna happen. Piston rings seal between 95-98% . This quickly degrades gradually to 90% bad --95% ok . sealing below 90% requires attention .
That's why factory catch cans are installed to some brands of vehicle that d`ont use magic piston rings LOL LOL

If you could see the sludgy treacle that comes out of a catch can tube when it is emptied you wouldnt think twice about fitting one.

Another thing to worry about.
I have just become aware of "Catch cans":
