K&N 57i kit or standard air box with new panel filter?

Hi guyss

Just wanted a few peoples thoughts on this? I currently have the K&N kits on the car, sounds great, but ive seen some stuff on here the suggests that the car doesnt actually benefit from having one of these and wondering if i would be better off having the standard air box back in with a new filter ?
 
ktec induction gets half decent results, the v6 airbox is one of the best its just sourcing one,

heard k and n induction actually gives a loss of power, so choice out of k and n induction or panel, id chose panel
 
I have a nice middle ground installed in the 200 Cup - the K&N panel filter. It gives me a warm feeling knowing that my air is being cleaned by a K&N filter and I don't know why.

My opinion is the panel filter is the best option. And that's a biased opinion. My days of loving the K&N 57i induction noise are long gone. I much prefer the clearer, non-drone breathing noises of the standard air box.
