Duratec Trackday Airbox

[The Wookie]

Afternoon chaps, I'm looking for a way to quieten down the intake noise on my C400 race car so it can be used on trackdays without fear of the noise nazi's. It's on roller barrel throttle bodies (presumably the same as the R500) and currently has a carbon airbox with a large internal foam filter that breathes outside the bonnet.

Caterham have a carbon item listed on their website but it's been out of stock for some time so I'm guessing it's been discontinued. Are there any alternatives? Not fussed about weight or performance particularly, the car is more than fast enough for a toy.

Isn't there one up for sale in the PH adds?

So there is! Thank you!
