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.

      Comments about K&N Universal Cold Air Intake:

      Don't bother to buy this sad excuse for a cold air intake system. This thing is a piece of caca and doesn't do what the description says it does. I put this on my built Nissan Skyline. They supposidley give you an extra 20-25 ponys under the hood. This is a LIE!! My Skyline with the factory air intake goes 0-60mph in 09 seconds. i bought this thing hoping ill get to 07 seconds off the clutch. I WAS WAY OFF. I put this on my skyline and my skyline went from 09 seconds too 17 seconds... Just to get the stupid car to go 40mph. This thing SUCKS! I've never been so dissapointed in a brand in my life. SAD!

      • Q:

        how easy/time consuming would it be to install this kit in my 2002 Mitsubishi diamante? Also, is it compatible with stock O2 sensors? What kind of a horsepower increase should I expect roughly? Are there any other parts that would help get more power when using this system?

          K&N air intakes are guaranteed to provide more horsepower and increased acceleration, but they make no claims for gas mileage. This K&N Universal Cold Air Intake (Part No) RC-5052AL is universal and not vehicle specific.
