Does anyone know the correct way to fit them?
Do you just sit it on top the belmouths and try and align the holes in the filter to the centre of them or are you supposed to insert the "trumpets" inside the filter holes, if you see what I mean.

They fit over the trumpets.Fiddly,but has to be done!

Thanks Jasper. The front one looks a pig to get to.

Hello Col996s

The trick is put your fingers just inside the first hole of the filter,
push it down into the airbox so you palm is now over the first trumpet,
As you pull your hand out, feel around the trumpet making sure its still
covered, the second one is alot easier, it's fiddley but you will know
when its right.;)

Oh . . just thought did you get a spray for it? I seem to remember mine was sprayed wih a coat of oil.

I like filters that cover the bellmouths they prevent things like small bolts that are supposed to be holding the front tank mount on dropping down there don't they Tim (Well I think it was Rattler that suffered this woe)
Been using them on my 996 for years, bit awkward on my 998s as the Shower injectors get in the way.

The holes are offset to line up with the bellmouths. There's usually a "front" marking on the filter to, as the leading edge isn't as thick as the rear.
Put your hand inside the filter, thru the rear whole and work the front hole over the bellmouth from inside. As you pull your hand out, fit the rear over the second bell mouth.

DIRTY BOY! :o

No I was told by JHP that it was pre-treated and did not need spraying.

I've got a small tin of Pipercross spray that came with my in-carbon-airtubes filters if you ever need some ;)

I have a set of Piper-X filters in the carbon air tubes on my 998R, got to keep the **** out of the engine some how
