The best cold air intake is the one built for your exact year and model, and AEM is one of the most recognized names in intake systems. AEM intake systems are engineered to improve airflow into the engine compared to a restrictive factory airbox, which is why they are a common first mod for Honda and Subaru owners alike. Our current AEM lineup focuses on short ram intake systems for the 2002-2005 Honda Civic Si, including the 22-508B — check your year and model before ordering.
AEM offers both short ram and cold air intake designs. Short ram systems like the ones in this collection mount the filter in the engine bay for a straightforward install, while cold air designs route the filter lower for cooler intake air. When shopping, look for generation-specific fitment, a reusable high-flow filter you can clean and re-oil, and hardware that bolts to factory mounting points.
Pair your AEM intake with related breathing mods: our Air Filters collection covers replacement filters, Performance Intercoolers help keep charge temps down on turbo cars, and Cooling covers radiators and supporting parts. Popular picks in this collection include the AEM Short Ram Intake System 22-508B for the 2002-2005 Honda Civic Si, and the AEM Short Ram Intake System S.R.S. for the same generation. For buying guidance, see our post Best Cold Air Intake for WRX.
Do I need a tune after installing an AEM intake?
It depends on the car. Some MAF-based engines run fine with a short ram intake, while others benefit from a calibration adjustment after changing intake geometry. Check what your platform's tuning community recommends for your year and model.
How do I maintain an AEM intake filter?
AEM uses reusable filters that can be washed, dried, and re-oiled at regular service intervals instead of replaced. Always use the correct AEM filter oil kit and do not over-oil the filter element.
Will an AEM short ram intake fit my car?
The systems currently in this collection are built for the 2002-2005 Honda Civic Si. Intake systems are generation-specific, so always confirm your year and model on the product page before ordering.
Is installation difficult?
Short ram intakes are one of the simplest bolt-ons — most install with basic hand tools in about an hour using factory mounting points, with no cutting or drilling on the listed applications.
