Bill Austin this will be completly different to this car but i have a fiesta 1.0 ecoboost can i still get the same chatter sound from a recerculating valve
Daniel Fletcher I can't say for definite, a cone filter will give you a lot more noise, if you took out your recirculating valve and blocked it off it would probably cause the noise but I'm not sure if It would have any bad side effects on such a modern engine.
