K&N's APOLLO CIS is a universal "Cold Air Intake System". 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 buildup is reduced which keeps the intake charge cool. Smooth internal features minimize air turbulence and maximize air flow. The Apollo is ideal for normally aspired engines up to 250BHP and turbo engines up to 350BHP. It comes with a standard 70mm base flange with a range of optional stepped adapters available to allow fitment to other intake sizes.
