Outer Limits 4x4 Board

Apart from the fact that K&N filters let a lot more dust in than paper filters, It is pretty well accepted that they foul MAFs on Rover V8s for the reason I gave.
K&N claim it doesn't happen if you oil it by the book Blah blah but sooner or later it will.
There was a scientific test done in the USA on all types of filters, which was referred to recently in an AULRO thread. Have a look.
This is a local test which backs up the US results
