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 build up 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.

Review part RC-5052AB

I installed the system on my Opel Omega B and I was quite impressed from the intake. The power has had a tangible increase. I recommend this intake system to all who are hesitating!!!

Just installed the Apollo yesterday without hooking it up to the origional intake baffle and I was quite impressed. Hooked the top part intake my forced (ram) intake today and ohhh boy. My Saturn Ion is now a bullet. Sounds nice, increased throttle response and so far it seems to be increasing fuel economy. Plus torque and hp. I have been enjoying K&N for a while now and now I'm completely in love.
