2003 R400 K-series air filter

Hi

Does anyone know the part no or have a link to a replacement standard air filter for the above? Car currently has an old Pipercross filter but I can't find a part no on it.

This will be for road use only so want some induction nose. Are there any alternatives that people use and how do they differ from the standard one (performance, noise etc)?

Thanks

Hi blackmamba if you look at the above thread on techtalk about "loose slave cylinder"I posted a photo at the end of the thread showing my clutch master cylinder but it also included a good angle on my K&N - after much deliberation and trial and error I nudged in some silicone hose then extended it as far away from engine as I could with the bonus that you do get a good induction noise as in effect its just over your feet.

Sadly it is high in engine bay and towards the back = warm air but short of reversing the whole intake I could not get air in from front to get cold air never mind seems to run really well and is easily accessible for maintenance etc.

Do a Google search for Pipercross PX600 air filter, you should be able to work out which one you need. There's lots of suppliers, as far as I'm aware it's a standard part .... unless you want it branded Caterham instead of Pipercross!

Hi

I received the new air filter today and looks to be exactly the same as the one that came off which is good. The 3 Dsuz fasteners line up perfectly and hold the filter securely. The black plastic tabs at the bottom of the filter don't fit the two long slots at the bottom of the backing plate though as they are parallel to the plate rather than at 90 degrees to it.

Is that how it is meant to be? It looks no different to before but intuitively I would have though the tabs on the filter or the slots on the backing plate should be a 90 degrees so they slot together.

Thanks

I'm puzzled. That's how I'd imagine they should be.  Does your filter look like this?

First, align the filter so that those long black tabs slide into matching slots in the backplate, and then swivel the filter upwards to engage the Dzus fasteners.

Or have I misunderstood something?
