Preferred brand of air filter (turbo cars)

[ChasingSand]

Currently using an Airraid filter but after this last trip (5 days) it’s collapsing in a couple of areas. Anyone have luck with a different brand?

I have OTR filters on my car, they seem to work well and are easy to clean.

Where did you buy them from? I found one I want but I don’t see it for sale online anywhere.

 

[Dodd]

Kartek should have them

I believe OTR is the new name for the R2C filters. I always liked those.

Walker engineering.
Best of the best to date.

Also, dry or oiled?

 

[Grease Monkey]

Dry. Order them with the dust sock.

R2C were tried and discussed a long time ago.
If I remember right, the consensus was not good and let sand thru.

my intake pipe is 3.5” and walker does not offer an off road filter with that ID. I went with a filter from HPS as it’s identical to my current filter. In the off season I will go to a 4” pipe instead.

Rated for ~350whp each. I got 4 seasons out of a $40 filter. No restriction, no dust, just figured it was time.

Yep. If you replace every season, not terrible. Beyond that, dusty intakes.

If that Donaldson is the one I think it is then it has the provision for an inner filter element also. So, you can maintain the outer/main filter element by blowing it out with air and not have to worry about damaging it. Also, you can put a debris filter on the inlet of that housing.

Correctamundo, but it's a single layer coarse filter, so I'd still be worried. It's supposed to change color with dust intrusion.

At $40-50 for a replacement, I'm just gonna replace every other year and not risk it.
