Hello,

Looking for a drop in dry air filter that is not oil based like K&N for the M37. The purpose was to increase HP after mods and tune. Wix was one option that I was looking at. But, I came across an unfamiliar brand today called DNA Motoring (https://www.ebay.com/itm/164657182456). Are you guys familiar with this brand and would you recommend? If not, are there any other recommendations that can be provided to increase HP with the stock intake (after mods and tune of course)?

I personally run PurolatorOne premium filters in my M56x and have done so for a long time. Seems to be high quality to me.

That was another option that I was also looking at. I will go with PurolatorOne as well. Thanks for the advice!
