AEM's CR-Z Cold Air Intake (CAI) features CNC mandrel-bent 6061 piping, tuned in both length and diameter to maximize power. Every AEM cold air intake is powder coated or polished and has TIG-welded fittings and brackets. The AEM Dryflow high flowing air filter traps dust and debris through an extremely durable synthetic media. The filter incorporates a metal screen on the outside of the media that enhances airflow and aids in keeping the pleating in the proper position. This cold air intake is C.A.R.B. exempt or pending exemption (50 state legal) and comes with complete installation hardware, comprehensive instructions, an AEM decal and license plate frame. Dyno testing was done on AEM's 11-12 Honda CR-Z 1.5L air intake systems and as a result an estimated increase of 4 horsepower at 5400 RPM was gained!
