GruppeM RAM AIR SYSTEMS epitomize the GruppeM philosophy of attention to detail. By replacing the factory air handling systems, increased airflow streams into the combustion chamber. GruppeM completes this by utilizing unique designs in order to optimize air flow for enhanced performance. One feature that truly sets GruppeM apart, is that they design their intakes to use fresh air instead of the hot engine bay heat. As a further benefit, they enhance the sound too!
