Corsa Apex Series Air Intake Systems offer a perfect combination of appearance and performance. Utilizing Corsa's long engineering history of airflow research, Apex Series Air Intake Systems feature Dynamic Flow Technology (DFT) to boost power output in your street or race car or truck/SUV. Each air duct is designed using DFT to include ideal mandrel bends and cross sections, an oversized system-matched air filter and precision fitted heat shield, which all together delivers more air volume, density, and air velocity. Apex Series Intakes are the perfect bolt-on performance upgrade, available with either a no-oil DryFlow 3D or MaxFlow 5 oiled air filter.
