Pic of K R400 with bonnet cutout? Anyone?

I am wondering about what air filter arrangement and what it looks like. 
 

I'd really like to reproduce the classic double K&N arrangement, but no info about whether that can be made to work.

Failing that is it Pipercross or ITG air filter and is it possible it as as simple as a deeper (higher) version of the standard Caterham part?

I would prefer to avoid having to engage in drilling etc.

Come to think of it is there a standard R400 air filter to fit on the existing base plate?

and in parts we have this:

might be worth speaking to Bruce,  Thumb Up  in relation to hole sizes across the models

Is this to fit your R500K, Anthony, or some other car?

Yes R500 K

It's the air filter I am trying to identify: and obtain a view / pic. I gather all dimensions are the same, following a chat with Arch.

Have you've studied this info on the Pipercross PX600 series?

I used the C603D on my 1.8K SS-R (which AFAIK has the same RBs as your R500).

I thought all K engines all ran with Pipercross half sausage filters which were screen printed with R500, AFAIK the ITG box filter was fitted to the VX engines...

The sausages can be made to fit a teardrop bonnet opening very neatly depending on what intake lengths you end up needing or choosing.

Yes here is my original one:


sadly ruined internally by age and replaced with one from CC that no longer says R500. 

My trumpets are as original. I'd like a half sausage that fits nicely in to the R400 cut out bonnet I have ordered from Bruce. 
 

How or from who I achieve that is the underlying question.

I would try Pipercross direct as Im guessing they did the screen printing for CC..... so they might be able to help or supply a plain one and you could get a stencil made and spray your own, checking what paint wont affect the foam, Pipercross may share what they use with you.

When you say "classic double K&N arrangement", do you mean something like this.  

These are Jenvey TBs with a Pipercross sock filter per pair (no backplate on the TBs/trumpets).  They fit under a bonnet without a cutout.

This on a 200bhp K-series.  Not sure how well they'd work out of the box on an R500 without mapping work.
