Thread: Air Filter Elements

I have been using Coopers/Fiaam air filters.

I just serviced the Disco and checked the checked the airfilter after 10,000 km. It looked ok until I compared it to a new one and it was discolored on both sides of the paper so it got changed.

I tried fitting the first one I grabbed (as I had two spares) and noticed it didn't fit very well in the air box. The rubber was a little larger than the recess it fitted into which made the sides bow in a little. I noticed there is not much lip on the side of the air box for it to sit in so grabbed the other one.

I noticed the sealing rubber was different on the two filters I had. One was smooth and soft while the other was same as the old one, a little rough and stiffer.

The stiffer one seemed to sit better in the air box so I greased the edges and fitted it.

When I bought the car I grabbed a RYCO filter and fitted it but didn't notice/remember the problem.

Anyone else noticed the bowing in sides and different rubber quality. Are other brands the same or better?

I guess you are right, but if you are a nitpicker like me , you will look in the intake and at the MAF for dust.
I usually use Cooper and they seem fine, but I think I also have a RYCO at the moment as spares. They both look OK.


My quote button does not work at present .

Correction, they are Coopers/Fiamm and a Ryco which is obviously a buy-in as made in UK so maybe the OEM manufacturer.

The Ryco I bought had Made In Poland on the box???
