... a cold air intake system.
The air comes in directly from the outside through the air filter and throttle body and into the plenums.
No hot engine-bay air mixes in.
Ironically, some of the so-called cold air intake systems, such as the conical filters which modify the airbox, allow hot engine-bay into the intake which as we all know is not good for power.
The problem with the Boxster's airflow is not in the air filter or air intake tube; it's in the throttle body cross section.
That's where Porsche chokes them.
So, if you install the TechnoPower Kit you do not need any other intake to gain more power. You may install it, but you may loose power.
Happy Boxsxtering,
