Hi all, I have a Focus St170 and wanted to know if it is worth buying the upgraded Automatic Air Deflector and whether it fits inside the snorkel or on top. Does it make any difference to performance ? Thanks, Loz

 

It wont do any harm thats for sure

 

It goes over the scuttle, covering the snorkel front. Can't do any harm, most say that the best induction is a panel filter in the standard box with the auto air deflector. Remove the resonator box for the induction noise.
