The Mazda RX-8 is a unique blend of sports car and sports coupe powered by the love-it-or-hate-it Wankel rotary engine. With perfect 50/50 weight distribution, over 200 horsepower on tap and room for 4 adults, there’s a lot to love about the RX-8. Rotary engines have fallen out of style in recent years but there’s a lot to love about them as well; namely a lightweight, compact package with smooth power delivery and a fun to rev 9000 RPM redline. These engines produce impressive power for their small 1.3 liter displacement and with an AEM cold air intake system; you can unleash even more Wankel-fueled fun with a guaranteed increase in horsepower.

The AEM 2004-2011 Mazda RX-8 cold air intake system will fit the Mazda RX-8 models listed below and is available in four colors: a chrome-like finish (21-485P), charcoal grey (21-485C), blue (21-485B) and red (21-485R). Air first enters the AEM CAI through an oversized AEM 21-2109DK Dryflow air filter positioned behind the bumper cover near the passenger wheel well to help reduce intake air temperatures and increase horsepower.
