You gotta breathe man, that's life. Your motorcycle has to breathe too! Motorcycle air filters aren't created equal, & a DNA air filter is one of the best around.
It uses advanced FCD (Full Contour design) technology to increase air flow. It does this by using the maximum amount of surface area possible. According to DNA, their filters have up 25% more surface area than stock. More air in makes more power, so why not remove the filter all together?
C'mon you know the answer to that, the quality of air going into your bike is important as well. DNA motorcycle air filters use 4 layers of premium cotton which block up to 99% of contaminants. Fits: 690 DUKE (2012+) 690 DUKE ABS (2013+) 690 DUKE R / ABS (2012+). The flow of this new DNA Stage 2 Air Box Filter Cover (P-KT6SM13-S2) combined with the DNA Stage 1 Air Filter (P-KT6SM13-01) is very high, 122.36% more than the KTM stock application.
