DNA KTM RC 390 (13-20) Air Filter and for Duke 390 ABS (13-16) add horsepower while letting your sportbike breathe better. The efficiency of DNA Filters maximizes breathable surface area compared to the OEM filters allowing you to get the most horsepower on any track day event.
I’ve always had great results with DNA filters and this one was no exception. Great build quality and fitment. The intake sound on the bike along side an open airbox lid is sublime! Also want to say that dealing with Paxton was a pleasure and all the help and support I received was second to none. I cannot say enough good things about this company.
