Currently only available for the 2001 - 2007 WRX & STI models.
The K&N Apollo CIS (Cold Intake System) is a cold air intake system incorporating a washable/reusable K&N High-Flow Air Filter. The Apollo’s shell reduces heat build-up feeding only cool air to your engine, resulting in improved volumetric efficiency and increased power gains.
The Apollo's specially designed shape increases volumetric efficiency and is made of durable lightweight material for cooler air intake. The Apollo incorporates a K&N famous cotton gauze filter which is removable for periodic cleaning 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 minimize air turbulence and maximize air flow.
