DNA Stage 3 Air Box

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

I have just received an email from Dino Nikolaidis, MD of DNA Filters http://f286.mail.yahoo.com/ya/downlo...Inbox&inline=1 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.

:clap: :clap:

Hi Ricky, the Tenere stage 3 is also being planned for production, it will be a totally different filter and airbox combination to that of the XTX/XTR, rest assured Dino is working on it, and soon as I know you will all know too.

DNA Stage 3 Air Box Kit for the XTX/R

Hi to all the forum members,
I am very happy to announce that at last we have completed a very difficult project the �XT 660 X/R DNA Stage � 3 Air Box Kit�
At the beginning we thought that the project would be rather simple..! but it was a pain in the�..! Almost 5 months, but we believe that the result will satisfy even the most demanding XT 660 owner.
The specifications of the DNA S3 are as following:

1. Complete DNA custom air box that houses 4 DNA filters.
We followed this route to separate the engine�s intake air, necessary for the engine to run, from the crankcase vent, the idle circuit and the AIS system.

2. The main DNA filter is a custom purpose designed elliptical DNA clamp on filter, with a built in venturi and a flow rate of 148,2 CFM @ 1,5 INCHES OF WATER and filtering efficiency of 98% minimum.

3. The 3 other small filters are standard elliptical DNA crank case vent filters.

4. The �rubber intake� features a unique design with a large built in radius, a conical profile and will fit any Throttle body from 48-53mm internal diameter. Additionally the �Banana shape� does not disturb the flow and positions the filter in the right place.

5. The air box is designed to accept the battery, the ECU and all the electrical parts that bolt on the stock air box.
Additionally it will accept the mud guard underneath and it will also have a �chain oil and dirt guard� on the left, to keep things clean and tidy.

6. The side covers are both laser cut, both have openings, also the left one with all the electronics.
The top has a massive opening to support the air flow and also allow the owner to view the filter and its condition.
The main filter can be serviced from the right side and following our calculations it would need cleaning every 20.000-30.000 km depending on the environment the bike is used, to keep the air flow always the maximum.

7. The AIR FLOW��..
As all of you already know:
a) Test 1:
Air box & std filter & snorkel
46.53 CFM (1318 lit/min) VE=0.539
b) Test 2:
Air box & K&N filter & snorkel
52.51 CFM (1486 lit/min) VE=0.608
c) Test 3:
Air box & DNA filter & snorkel
57.19 CFM (1619 lit/min) VE=0.663
d) Test 4:
Air box & DNA filter & Without snorkel
59.52 CFM (1685 lit/min) VE=0.690
e) Test 5:
Air box & DNA filter & DNA Stage 2 filter & snorkel
79.19 CFM (2242 lit/min) VE=0.918
f) Test 6:
Air box & DNA filter & DNA Stage 2 filter Without snorkel
79.89 CFM (2262 lit/min) VE=0.926
g) Test 7:
Air box all open Without filters, side cover, snorkel
(this test is for reference only the bike can�t be used on the road in this state)
88.6 CFM (2509 lit/min) VE=1.027
h) Test 8:
DNA Stage 3 Air Box Kit AK-Y6E07-S3
111.9CFM @ 1.5 Inches of water
This result is filtered clean air! And if we compare it with the Test 6
The very popular DNA stage 1+2 application & No snorkle
we have +40% increase in air flow..!!!!!!!:winner:
If we compare it with Test 7 (no filters or side covers, air is NOT filtered,
the stock air box cannot be used in such a form)
we have +26.3% increase in air flow.

During this week we will complete all the parts in production form and I will post more information and photos.

I would like to thank all the forum members for keeping us motivated and any questions that you would have, I would be delighted to answer.

And not to forget we are already designing a DNA Stage - 3 Air Box Kit for the XT 660 Z 08�-09� that will take care of many problems and flow issues related with the stock air box!

Best regards to all of you and please accept my apologies for not being on the forum lately, as we have so many projects running.

Hi Rick,
I have replied to you, it is very strange that you did not receive my reply?
Our next S3 project will be the XT660 Z, but we will have to see how the DNA S3 XT660 X/R will sell, so please give us some time.

Regards,

Dino

Is there any idea on a price yet please???
