Found another cheap airbox that works, here -->http://www.uniflow.com.au/contents/en-us/d136.html

Unifilter are Australian owned and will make customised units for you

I ordered a 300mm long version of the SU filter (Dimensions: L x W x H 300mm x 140mm x 75mm) and they cut the holes for the throttle bodies off their template for the foam OEM filters they stock as std spares (I needed to cut out a tab on one side of each hole to fit the tang on the throttle bodies as aluminium is apparently less stretchy than foam - but they would have done this if advised)

I was going to purchase as per Kev's recommendations but with the current exchange rates this was a lot cheaper (AUD$150 plus GST and very reasonable freight) and seems a nice unit - though not as quick to remove for cleaning as the ITG Dzu fastened design (this could be improved by making up posts that remain attached to the base plate with nuts on the top if required)

I was surprised to find the unmodified crankcase hose re-routes happily beneath the base plate to the RHS (facing forward) of the throttle bodies so drilled a hole there for the attachment and the air temp sensor fitted neatly ahead of the 1st throttle body without fouling anything.

Currently running one of Kev's ("He is a genius" - A. Schwarzenegger) maps for airbox and cans and the bike is now an absolute joy to ride especially off a closed throttle and it is both noticeably more muscular plus easier to ride in cruise mode - win , win , win.

I wonder, as I live nearby, will Kev please tell me where he gets his bikes dyno tuned???

Great air box, well done mate not seen that design before.

I get my bikes Dyno in Nerang just down the road from you, go & see Steve at Power House he is fully accustomed to tuning these KTMs.

Welcome mate.

I would not bother with the standard air box is just cant flow the numbers, get yourself an open air box that has been proven to give great gains.

I have just asked George for a ITG JC30-80 air filter base plate :D
Now I have to buy the air filter and I think a RC8 stack too.
Any recommendation where I can ask for ITG filter in Europe?

Hey Doody, thanks for the write up. Ordered the same yesterday.

Myles Gooch from http://uniflow.com.au wrote to me regarding the filter + baseplate kit for the 990 KTMs:
This kit will be available from our website soon. We will have two versions. One the same as the kit pictured using bolts to attach and early in the new year a new version with a push button style dzus clip attachment for easy removal. See Video. The Bolt style will retail for AU$160.00 plus AU$20.00 freight to NZ. The kit with the push button style mounting kit will retail for AU$220.00. plus AU$20.00 freight to NZ. The only holes that you will need to put in is the breather and temp sensor. The kit also includes the rubber spaces to go between the intakes and plate.
Great communication with him, super fast and friendly! I am impressed.

I find a company at Greece that can manufacture custom filters so I order a pair for 990 smr.
installation was easy and the top of the filter now just touch the bottom of the tank so the total available clearance used.
velocity stacks are in place and there is a clearance of 1 cm.

These filters are full custom.
I gave them exact dimensions that I need and they made these two.
So there is no any link for the moment.

Well Kev sometimes is wise to have the permission in order to advertise something in public.
Today I contact the company that made the filters and they told me that they can make custom filters
on request as long as someone give them the specific dimensions.
of course for 990 they already have the dimensions of mine so they can accept orders.

For those who like to take the advantage of the total available space around the intake area for any bike is a nice and cheap mod.

There is a large gap between the throttle bodies and the velocity stack.
there is no way to secure a clamp properly that's why I made those two acetal rings.
now there is sufficient surface for the clamp.

Ok, I could be totally off on this topic, but is there any merit in trying to use the old school method of using a cone type K&N filter directly on the throttle body?

As long as there is enough air gap around the lip & on top of the stacks.
