Am I right in thinking that I would be best sticking with the standard paper filter to increace engine life (I'm hoping for 100k miles plus)?

Hi Deiaccord,
First of all thank you for your time and aggressive comments; I have joined the XT 660 forum to answer all requests and concerns that users would have and finally put an end to all the bull�t that people hear, using independent tests, plus tests that we do with our Hi tech equipment.
The post that you have seen at the WWW.ADVRIDER.COM forum amazed us also, not even our advertizing department could do better! That was a brilliant presentation! But unfortunately for our competitors and fortunately for DNA it is 100% true, and we know it very well because we see it every day and know it is time to spread the word, so people will stop thinking that the DNA filter is just another filter that looks like a K&N.
So to start I have attached a test done by the French motorcycle magazine MOTO. Τhe test was done unbeknown to us AND TO ALL THE OTHER manufacturers; the mag also purchased the filters from random stores and no one knew anything until the magazine was published.
The test is in French but you can easily understand it. To guide you thru, they used a Honda CB 1300 S and tested, DNA, K&N, BMC, GREEN and the stock Honda paper filter. They used the test facilities of an independent laboratory called �CETIAT le Centre technique des industries aerauliques et thermiques� the French forum members should know it.
They tested:
�
Fitting and sealing of the filters
�
Filtering efficiency
�
Air Flow
�
Performance Dyno tested
�
Evaluated the overall quality
�
Simulated the actual cost the user would pay for 72.000 km
Well guess what� the DNA filter was best in all tests except the simulated cost�
��..DNA was second with 9 euro difference! But do you care? If the filter you choose to use is First in filtering efficiency, First in overall quality and fitting, First in performance, First in air flow�! Does 9 euro make a difference for 72.000 km of usage?
If you try to divide 9 by 72.000 the calculator displays 0.000125 euro/km thats what you have to pay more to use the very best of all the filters.
And finally you must understand that the DNA filter flows more and performs better because of its DESIGN and the superior materials we use, we at DNA will NEVER produce air filters that have a filtering efficiency lower than 98%, that is the same filtering efficiency you are getting from your Yamaha paper filter with almost half the flow!
I hope you will enjoy reading the attached pdf with the test.
Looking to hear your comments,
Regards
Dino
P.S. stay tuned because we are almost done with some back to back testing of the DNA versus the K&N XT 660 X / R filter and you will be SHOCKED��with the results!
