That said there seems to be a lot of nasty abrupt bends in the Zetec inlet system.... surely a smooth radius using something like a CDA inlet system would be better even if the routing was the same.
http://www.bmcairfilters.com/infoCDA.aspJust mount the barrel filter just in front of the heater... Duct the air round in a single smooth radius to the filter housing then onwards to the inlet manifold throttle body assembly.
Andrew,
This very much mirrors my own current thoughts. I looked hard at the BMC and then switched to ITG's Maxogen. At the moment, we're still looking at the siting/routing issues . One thing for sure, I need to take out what is in effect a nasty right angled bend at the air filter body.
I'll put up a post as I go along
regards,
G
