Obviously you don't have to listen to me at all, and do the f@@k you want mate, but I would rather side with caution methinks.

Yes it matters, but nothing worth worrying about IMO on a T3, just my opinion!!!!
Ford put the re-circ dv on there as the customers at that time probs wouldn't appreciate chatter
