Subject: K & N filter or not

I used to have aftermarket filters but after getting a boost fluctuation using a k&n. I put the paper back in and the fluctuation went away. You don't get smooth air flow with most aftermarket filters which was the issue with my car. I had my stage 2+ Octy VRS on a rolling road using both filters and there was no increase in power. The paper had a smoother graph as the turbulent air was causing the maf to read incorrect. The filters on the Kuga are huge and the paper filters easily can filter more air than the engine needs so works perfectly fine.
I don't think I will bother fitting any other airbox to this car as I it works fine as it is. The most I will do is possibly a remap but that is it. No matter what the companies say they don't filter as well and I don't want any dirt getting into the inlet.
