Any problems with K & N Air Filter?

[Ice Man]

Was going to buy a K & N Ait Filter today but then somebody told me it was not very healthy for turbo cars. Any of you guys had any problems??

I reckon there is no problems after looking round some of the previous posts on the subject but thought I would check anyway.

Cheers

They're supposed to filter better than standard paper elements. The HKS foam filters don't......er filter that is.

This test was done on a Ford Focus air box with after market panel filters fitted.
The Japanese brands don't make any for this vehicle, but it show the typical characteristics
for the filter type. I would expect Blitz mesh to be as pipercross but with the lowest dust
capacity due to no oil and very thin media.

Notice the face velocity, High velocitys can suck dirt off of the element
Also note the differance in restriction. Not much in it concidering the down sides.
