Unsurprisingly the most popular entry level performance upgrade is an aftermarket cold air intake kit with handheld PCM programmer.

JLT Series 3 Cold Air Intake
The JLT series 3 110mm CAI is the most free-flowing CAI kit available (estimated to be a whopping 1435cfm @ 28" H2O depression) and I bought that together with an SCT X3 handheld tuner. Installing the JLT CAI and uploading the Brenspeed 91 octane (95 RON) tune into the car's PCM was a breeze. The engine immediately felt more responsive and the low rpm "lag" of the drive-by-wire throttle was gone. There was a noticeable induction roar when pressing on the throttle which, when combined with the soundtrack of the engine, was very intoxicating! Acceleration through the gears was noticeably stronger, especially in 5th gear at highway speeds, making the car so much more fun to drive. |
