Thread: Performance air filter

I am also curious about as I was thinking about it the other day. Is there a high flow aftermarket kit to replace the Donaldson?

What vehicle/engine ?
Are you talking about the Big barrel on top at the back ( Donaldson type ) , I don't think you will get a filter with more surface area , ease of flow, than that , and one that still filters, a lot of "performance" filters perform but don't filter , just keeps the rocks out.

For the 4bd1, so yeah the big barrel at the back. Thanks for the info!

I have a td5 and I have purchased a carbon fibre performance air filter.
Just was curious of other peoples thoughts .
I haven't fitted mine yet so can't give any feedback

Which manufacturer? Are you talking about the element or the housing?

There are several threads on here with actual filter test results for "performance" filters. Air Filter Tests (Finally)

In almost all cases (with a 4x4 and especially a diesel) you are better off with OEM - or with a product from Donaldson, Fleetgard or MANN FILTER - unless you want to shorten the life of your engine...

Agree with isuzurover.
I think that the point is cleaning the air effecively at the volumes the engine needs. I have read that the 4bd1 needs a flow of 275 cfm which is much higher than most "performance" filters can handle.
I am definitely no expert but my opinion is that effective cleaning is key.
Donaldson etc are designed to work at the required flow rates in construction or harsh environments. In my eyes that is the best protection you can get.
