Whats the little green filter hiding behind the battery box ?

Air pump.. used by the car on cold starts to pump extra air in for emissions etc..
used to go to std airbox so has its own filter instead.

Whats shown is a bot of Green Dynatwist and RamAir. Green flexi duct and aux filter (RamAir also used, but not to hand ont he day I fitted it)
