I'd bin the cone filter idea, as you will be increasing the ACTs with this, as it will be sucking in hot air from the engine bay.

If you are running a 2wd intercooler, you will see vast improvements running the Escort item and it will still retain that factory look. This is the one we did for Jim Green's car - looks like it was made for it .





This set up would be more than adequate up to 400bhp .
