The K&N Apollo Closed Air Intake System is a performance air filter induction kit that includes a washable/reusable K&N High-Flow Air Filter. The Apollo's specially designed shape increases volumetric efficiency and provides the benefits of an open cone filter and standard air box in one unit. Heat build up is reduced which keeps the intake charge cool. Smooth internal features minimise air turbulence and maximise air flow.The Apollo's outer shell is made of a durable lightweight material that helps keep incoming air cool as it enters the engine. K&N's Apollo system includes a cold air hose, with a specially designed radius end cap, so cooler outside air can be directed into the engine.The Apollo is ideal for normally aspired engines up to 250BHP and turbo engines up to 350BHP. It allows for improvements to airflow while retaining the benefits of a closed airbox.The K&N Apollo Closed Air Intake System contains a general multi-lingual installation sheet with pictures and is backed by K&
