As has been mentioned in several threads, the MNNTHBX cover doesn't seal properly on the DNA filters as their mounting flange isn't as tall. The filter slops around in the airbox even with the lid fully tightened down. It actually will allow some vertical movent as well, so its not a good seal and can let contaminants post there filter. Note however, the filter does fit and seal fine in the stock airbox...
I emailed Greg at MNNTHBX asking if they would consider making the relief a bit shallower in future to increase compatibility but that's unlikely to happen I think.
Forum user bahawton suggested weather stripping, and that's exactly what I've done. I bought some closed cell self adhesive stripping - they had some thinner white open cell style as well but I thought the closed cell would probably seal better and last longer. The open cell white stuff would have worked fine as this was a much snugger fit.
The MNNTHBX lid is too nice to not use... Happy it seals as expected now.
