When the 996 replaced the beloved 993 as Porsche’s current model of the 911, there were many who initially refused to accept it as a 911. Odd-shaped headlights? A water-cooled engine? How could Porsche have the nerve to call this a 911?! Well it didn’t take long for loyal 911 followers to realize that looks weren’t everything, and the 996 was not only a suitable replacement for the 993, but it also brought with it a host of technological advancements that simply made it a better car. As with any modern car that uses a computerized engine control unit (ECU) to monitor and optimize performance, the 996 can benefit from simple, cost-effective modifications that can enhance performance, as well as the overall driving experience.
