It has a forge dump valve not sure what model.

I'd like to fit a standard recirculating one back on but had a look and it's not as easy as I thought, I've a front mount fitted "Airtec" and a K&N inducion so i'm not sure if I can refit the original with out undoing all the other stuff. The bleed hose is attached to the DV and the main house is also attached but the hose for redirecting the air into the air filter or airstream is the other side of the engine blanked by a plug.

This is the kit thats fitted: http://j-w-racing.co.uk/product.php/..._focus_rs_mk1_
