You have the main filter the one that looks like a bog roll, lets call that one Stage 1

Then DNA pioneered and designed a top cover filter which replaces the snorkle allowing yet more air in the airbox, that would be Stage 2

Then they have developed an additional filter which has shown sensational results and that is the side cover filter Stage 2(3) the (3) between brackets means it will only give stage 3 performance when used in conjunction with the other 2.

So if you want top performance you need all 3.

Now onto the shipping costs when ordering multiple items. I have myself questioned DNA hoping to obtain a reduced cumulative shipping price when multiple items are ordered however Mr. Nikolaidis put me on the spot when he explained that each item is shipped by UPS Courier Worldwide and each is priced in relation to their bulk sized box and weight and if you throw all 3 in the same box you end up nonetheless with a great big box which weights a lot.

And that my friend is nothing I can do about it, however, DNA do throw some case candy in the bargain allowing you to buy a much needed cleaning kit containing 2 bottles one is the cleaner and the other is the reactivator oil, at half the normal i.e. �5.50 as opposed to �12.

And finally don't forget that if you buy from me privately and not from the e-dna website, you will receive a forum discount of 10% over the retail price of each item.

The choice is yours.

If you buy the stage 2(3) filter you also get 2 power commander maps one for standard exhausts and the other for aftermarket ones like Akrapovic etc.

I am no novice to the postal 'games', lol Thing to do is see the cost on the box when it arrives and for all three it wouldn't be anything like the 45.00� DNA asks. I digress though.

- The charge is for 'post and packaging', so you should always expect to pay a bit more than just the postal cost for the time and materials involved in packing it up and getting it ready for the courier.

- Every international courier I've dealt with works in 'volumetric weight', in other words they have some sort of formula which turns the size of the package into a 'weight' which they charge you. This means you end up paying a lot to send big items, even if they don't weigh very much. Try pricing up the cost of sending a piece of sportsbike bodywork (weighing a few grams) across Europe. I suspect this is why DNA can't reduce their postage costs - every extra item you put in makes the box bigger, even though filters aren't heavy.


Re: Power Commanders.

They are the most common brand of a range of products designed to allow you to alter the fuelling of a bike with fuel injection, in order to maintain the correct fuelling when aftermarket parts such as exhausts and (in this case) air filters are used. They are plugged into the bike's Engine Control Unit (ECU) and tell the ECU to inject extra fuel depending on the engine RPM and throttle opening. This is important because by fitting a filter which allows more air in, you need more fuel to maintain the correct air:fuel ratio.

Their website is here - http://www.powercommander.com/powerc...r/default.aspx - but any decent bike shop should be able to source and fit one for you.

To make it work, you need a 'map', which is loaded by connecting the Power Commander to a computer. It sounds like you will get one supplied with the DNA kit, and the shop that fits it should be able to load it for you.

Now that's a good starting point, but in an ideal world, you should put your bike on a dyno and have that map altered slightly to suit your exact bike - your engine will inevitably be slightly different to the one DNA have used to produce the supplied map. Again you should be able to find a bike shop or tuner near you who can provide this service.

Do I take it that this 'power commander' is a permanent fixture of the bike or is it a tool that is used then placed away for other bikes?

I went to the sight mentioned but could not find a 'power commander' for the XT660Z. I have the Tenere.

Can the stage 1,2 and 3 be bought through this forum?
