Have you got the air filters yet?

If so what they like?

So whats the best overall filter for the Ducati's (manufacture type), that you guys would say gives the best flow?

if
 

your using filters in the airtubes, be sure to check the bolts holding the locating pin at the front of the tank are tight.

one of mine became loose & fell in the belmouth of the vertical cyl. bent valves & a snapped closing lever was the result:(

I have just fitted a C/F air box and up graded my old JHP filter with his new "K&N" style under tank filter system, it seems ok and as JHP have a reputation to uphold I can only think that maybee they have done their sums as to wheather these work ok.

Have a loom on their web site for a piccy of them fitted to a 998.
