Has anyone had any use of the above with the induction cover?

I currently have a Blitz SUS filter on the car - there is plenty of cold air via a carbon induction scoop directly over the filter and two additional cold air feeds from the wing having replaced the resonator box. I do love the sound it gives, but, i've started looking at panel filters to compare performance.

Just wondering if anyone has any experience of the above.

In case you don't have and are wondering what it is here is a link -
Blitz UK: Products > Air Filters > Blitz Ind Cover

 

Dont know anyone who has tried these but have seen a replacement airbox (JDM) on a car before - they crop up occasionally on flea bay but no knowledge on how good they are - do know that APEXI filters have the best record for filtration/airflow.
Sorry bud not much help - but will be watching to see if anyone else does know...
