MX5 Miata intakes come in several brands and we carry the most popular choices. An MX5 Miata intake lets the Miata motor breath easier and make more power. The Miata K&N filter below is merely a highflow filter that drops into the existing factory MX5 Miata airbox. The Racing Beat and AEM intakes below are complete replacement open intakes which provide the highest possible flow and horsepower gains but necessarily make more sound because of their open designs.
