This news is so important that it has been posted here.

I have just received an email from Dino Nikolaidis, MD of DNA Filters he has now informed me that a stage 3 filter for the XT660X / XT660R is finally in production and will be available for sale soon, also I am waiting to receive pics and installation method together with the relevant test charts however I can anticipate that according to the initial findings Dino has announced an increase of airflow of 40% over a competely open airbox without filters!! Which means this will signify the best optimum a/f for the XTX/XTR bikes which have so far suffered from a restricted air intake from factory.

Please also notice that the first producton Stage 3 filter will be sent to Kev in Australia for test who will then fill us in with his results.

I am vey exciited about this news and I am eagerly awaiting for these to reach you all.

Well done Dino and DNA for your excellent service and dedication. We have been asking him to make a Stage 3 filter for some time and now what was our dream is about to become reality.
