For those who use the MotoHooligan airbox - How often do you clean the filter, and what method do you use.

Is there a source to purchase spare filters?

Also, have some guys fitted the stacks (little intake jobbies) from the RC8 to help gains? I seem to remember something but couldn't find the thread. (What's the part numbers and price?)

Filter is the same kind of filter used by K&N and they advice to clean it every 25K km or something like that.
They have a kit for 10 or so euros with a cleaner and spray so you could use that, just remember to leave it to dry completely before spraying it again.

I havent cleaned mine yet but as Jermo says just use the K&N stuff. I have the shorter trumpets from RC8 in mine. They are silly cheap (about 2 quid each as I recall) i mine. Cant recall the part numbers but any KTM dealer will be able to find them on an 08 RC8 microfische thingy. They do give a noticeable gain but I fitted mine after having the head work done so dont have exact figures.

Thanks guys.

25K LOL - I have to be more concerned about dust and cobwebs as it sits in my garage!

Thanks Bert.
