I will be taking delivery of a Cooper S Convertable next month. One of the dealer installed options is the JCW air filter kit ($550), and they offered to install a pully modification for around $600. The salesperson said would add 15HP and really improve performance here at the higher altitude in Denver. Anyone had this done and is it worth the price? Did you have any problems with this modification? Advise please.
