K&N VS PIPERCROSS???

So whats the best I have a K&N fitted to my F and I love it.
Then the other day I found this .....


Pipercross Cold Air System
This is what we refer to as 'The rice burner' this is the ultimate cold air system for your MGF (or Lotus Elise) this features a huge Pipercross trumpeted filter enclosed within a cannister. This filter was originally designed and used on the Australian V8 Holden touring cars! So it has enough capacity for your 1.8 K series! The filter is attached to the throttle body with a silicon hose and the flexible cold air pipe and trumpet picks up air from the wing vent. Never mind all the other cold air kits, we've been there and done them all - this filter will produce the same if not more than any other kit on the market - this is not an idle boast and it is somewhat cheaper than the opposition!
You cannot buy this filter anywhere else and at £200 inc. VAT, you will not do better. Postage and Packing £12.00 UK mainland only.

I do have a pipercross filter that will fit and I was going to make a inclosed induction kit like this HAS ANY ONE GOT ONE FITTED
FOUND IT ON THIS SITE http://www.moto-build.com/mgfparts.html

I can't see that flowing more air than my K&N Apollo, not worth the cost TBH.

I have the Pipercross Viper kit fitted. Very happy with it. Only cost me £50 second hand, though.
