Recently added a DNA filter to my 2017. No other mods except Mivv double gun exhaust. It's really woken up the bike with smoother and better power delivery. Pulls very nicely. Very pleased and well worth looking at.
Debated between the DNA and K&N and it appears the DNA , although initially appearing similar is very different in so far as it increases the surface area of the filter material, adding considerably to the flow rate. Whereas on the K&N it follows the same design as original and just changes the filter material. I can defo feel the difference and would highly recommend.
