Can you not get some suzuki ones? They're quite nice little rubber things, with a nice lip around them to easily mount an air filter backplate. The downside is they're quite short though. I think they're about 13 quid each from Suzuki, but i got a set from ebay, had to buy a complete airbox for them but was only a tenner.

One other thing that might be useful is that on the K1 GSXR1000 there are two different lengths of trumpet on every bike, cylinders 1 and 4 have really short trumpets and cyls 2 and 3 have longer, presumably to spread the torque out across the rev range a bit. I bought two complete sets so I had 4 long and 4 short, this way I can mix and match to find what works best for me. Don't know if this was carried through to the K4 bikes though

Couple of pics of them in my golf, these are the longer ones

They look good are they the same diamiter as mine.

Or try here

ID of my bodies (K1 GSXR1000) at the inlet is 48mm, haven't measured the OD though. I imagine the best bet would be to source some K4 trumpets.

My bad, it's the K1 GSXR750 that has the mixed length trumpets, the '1000 ones appear to all be the same length.

K4 bikes also appear to have very similar trumpets though (inlcuding using mixed lengths). There's a handy parts microfiche here that shows the parts (trumpets are in the air cleaner diagrams)

Thanks for the help i had a word with my mate who has a mate that strips bikes and has loads of spares so im going to see what hes got on monday.
