Paper Filters are rubbish.

These are not cheap but they work and will fit on top of a normal snorkel tube.
The earlier types have a ball bearing spinner inside that throws out the dirt at very high speed.

Yes, a few different brands and types.
from the traditional Donaldson plastic bowl precleaner, from memory is something like 70 dollars for a 21/2 inch.
I suspect the SK types to be 250 dollars ? in 21/2....see our Cummings agent.

For something that effective $250- isn't bad.

Or look out for a dead Dyson on a roadside clean up day. I can see it now on top of the D2. HEPA clean air into the engine.

This is only after 5000km and less than 200km of dirt.:mad:

I have now gone to a K&N. This was the first time in over 10 years that I have run a paper filter in a vehicle and this is what I found. I have otherwise run K&N and always found anything south of the filter absolutly spotless and that included plenty of dirt tracks and road.

For those of you that aren't familiar with the filter. This is the engine side of my Discovery 2 filter.

I know some are going to tell me how good their paper filters are and I must have had a bad quality one (2 actually, one Ryco). And then I won't be able to do a proper comparison since I have fitted a snorkel at the same time I have fitted the K&N.

Nope. It rained last week (after this filter was changed), that was the first time since late May in think.

Happy Days.

so i guess that rules out simple staining due to moisture in the intake system.....



is there any reason not to spray some oil onto the paper filter....?
I've noticed some of the original nissan paper filters come pre oiled....but don't know if the material is the same.......

maybe someone on here may know....?

Follow someone's dust for 10 min then check your intake tract...

It's going to be red :)

Sorry, but I've had the K&N and they are far worse - real world.
