The Apollo Cold Air Induction System is designed to bring cooler air to your intake system. Cold air is denser and contains more oxygen and cooler engine air inlet temperatures result in more power. The Apollo system works on any vehicle because it features its own filter/housing unit. Simply remove the stock airbox and then connect the Apollo unit to the vehicle’s intake hose or air flow meter. K&N offers a range of adapters to facilitate this connection. Then connect the cold air hose to the Apollo and position the other end behind the grille. The Apollo unit and hose should be secured in position. In the event of inclement weather, reposition the cold air hose to prevent water intake.
The Apollo’s specially designed shape increases volumetric efficiency and provides the benefits of an open cone filter and standard airbox in one unit. Heat buildup is reduced, which keeps the intake charge cool. Smooth internal features minimize air turbulence and maximize airflow. The outer shell of the Apollo is made of a lightweight, durable material that helps keep the incoming air charge cool. A selection of adapters is supplied with the Apollo so all hoses that were connected to the OEM airbox can be attached to the Apollo unit. The unique Apollo K&N air filter features a large increase in filter area over the stock airbox filter, resulting in a huge increase in airflow and a greater capacity to capture and hold dirt. The filter is easily accessed by removing the 8 bolts and separating the housing and flange sections. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.
