Air Filters - Closed or Open Ended?

Hi,

We've recently bought a 1990's Prado which seems to be in quite good condition for its age. Looking at Repco they sell 'closed' air filters and 'open both ends'. The closed ones seem to be a bit more pricey than open-both-ends. Is there any advantage to either? I can't see this discussed anywhere online.

I've read on here that K&N may not be recommended for dusty areas, and we use quite a dusty old road. However, I also see Ryco O2 Rush Performance filters which look like they might handle dust better. Are they any good?

Thanks!

Alex

PS - you can see the horse paddock we drive the Prado up and down here https://horsetrekn.co.nz/paihia-weat...bay-of-islands

If it's open at the other end too it'll suck the shit straight through. Closed it should be not open.

I just checked Repco’s site to look at the open ended air filters & entered my rego number. Nice that it brings up all your car’s details for you to confirm before shopping for lubes & parts. I have one MAJOR problem with their recommendation of Repco branded Dex 3 auto transmission fluid coming up as the first in line recommendation. The correct Penrite LV fluid 2nd, and Castrol Dex 3 3rd. My car is an 05 V6 5 speed auto. Dex 3 should not be used. How did they get that so wrong? Shouldn’t even be listed for the 120 Prado 5 speed.
Supercheap not too much better having Penrite FS fluid recommended above LV fluid when you use their in store search touch screen. Although, in that case FS fluid can be used. That’s what I prefer to use. But Dex 3? Common?

Brett1979 I reckon they are getting confused with the early 120 series diesels that had a 4-speed A343F auto trans (same as used on all the 90 series autos), and this required (at least on the 90 series) Dexron III. No reason they can't get it right though, or at least prompt you for more info like the tranny model if they are not sure.

I wonder how many people have been caught out by this, I bet many just think ATF is ATF and don't realise how different some are.
