better airbox

[GooSe77]

Has anyone fiited a better flowing airbox into a 75 series ?
Mine is starting to rus away so I might aswell upgrad at this poin since the 12H-T likes more air ...

The 12HT breathes less than the 3F and 1FZ FE, but they all use the same airbox.

So you mean there won't be much of a difference ?

Probably not an option for you but....

I have ran one of their air boxes in both a v8 swapped truck and a diesel. Excellent product but they are large and expensive.

Not unless you plan on spending a lot of time at 4000+rpm. I think the Landcruiser airbox has extra capacity built in to allow the filter to go for longer in dusty conditions.
I think the HDJ78/79 has a slightly larger airbox, but I cant see the point of spending up big to get one when your engine doesnt breathe hard enough to use. A 12HT does its best work at 2500 or so
There are calculators for airflow engine cc

Well, I'm not chasing high RPM, rather better spool up and thought a beter flowing airfilter might help a bit ? I still have the original zyclone filter onmy snorkel. but I understand you, lots of cash for a little to now improvment ....

The other reason is the Toyota filter and box takes up a bit of room, anything with more flow would have to be bigger. Donaldsons have a range of filters that have higher flow rates but are more compact. Im not sure if there is anything in the correct size though
