Overview

The Boxster was treated to the engine from the entry-level Cayman. This was essentially the same as the previous power unit, but had Porsche’s VarioCam Plus valve management with continuous adjustment of intake timing (VarioCam) and variable valve lift switchover (Plus). This gave an extra 5bhp, at 245bhp, while maximum torque rose to 273Nm.
