Has anybody fitted a DNA air filter to their Desmo or know if they're any good?
For the stuff that has to go forever (work vans) I use oem paper elements. Once I was changing one and set the old one on edge on top of the box. In 20k miles it (paper with a dry foam top layer) grabbed so much fine grit it was running out of the filter like water. Really puts in perspective just how much damage an oiled gauze filter can do. For stuff like bikes where power is the primary mission, I use the oem filter. There are people who can tune for less restrictive filters, but most people who drop in an oiled gauze element end up losing power. UNI, if available, has always been the better filter. Apollo has one or one like it. They are oiled open cell foam. We knew 30 years ago UNI filters grab finer grit with less restriction than a K&N. Unfortunately for the masses, K&N did the better job of marketing.What do you use Desmohp?
