When selecting the right cold air intake for your ride, several CFM options are available depending on the style of the intake and the manufacturer. What is CFM you ask? The literal meaning is, “cubic feet per minute". Simply stated, it’s the flow of a 12”x12” cube-worth of air through a given area. Think about it, you inhale and exhale around ¼ of a CFM of air with every breath. Your engine inhales about 150 CFM. So, it’s easy to see how important the CFM really is.
Why Stock Intakes Won't Get the Job Done
Regardless of design, brand or fuel burned, every internal combustion engine needs air. Factory air intake tubes are designed to minimize engine noise by adding restrictions and baffles. Sadly, this also reduces the amount of air that flows into the engine. By adding a K&N cold air intake or a larger mass airflow sensor, the engine is able to draw in more oxygen and build more horsepower.
The Best Air Intake Brands
Companies like K&N, Volant and AEM, dyno test their cold air intake kits to ensure air smoothly enters the engine, for reliable power and fuel economy gains. As it turns out, installing a Volant cold air intake or an AEM cold air intake takes less than an hour with basic hand tools. Best of all, having an understanding of what CFMs are, makes picking the right accessories a breath of fresh air.
