Hi,
I have a Gruppe M fitted to my FN2 but have been told these can be restrictive. Can anyone tell me what is restrictive about them please as I thought the ram air affect would be better than a cone just sucking air in and the cone surface area is much bigger than the OEM panel filter.
Is it because of the smallish gap from the bonnet scope to the air box? Air box size?
Would a second air feed into the box remove this restrictiveness if it is restrictive?
Thanks for any answers and advice.
Cheers
Dave
