AEM Cold Air Intake System
Application: Mazdaspeed 3
Years: 2007 and up
Part Number: 21-642

The AEM Cold Air Intake features a mandrel-bent 6061 aluminum inlet pipe for durability and light weight. Each AEM Cold Air Intake system's length and diameter has been tuned and tested to work with an engine's harmonics (resonance frequencies) to help carry more air to the inlet valves across the RPM range.

Each AEM Cold Air Intake features one of AEM's revolutionary DRYFLOW filters. Their unique non-woven polyester element is independently tested to filter out 98.6% of airborne fine dust in initial efficiency, with an industry leading cumulative efficiency of 99.4% (cumulative efficiency is the average for the test cycle). The DRYFLOW also filters down to ONE MICRON of particulate! Competitors claim that as the filter gets dirty, it filters more efficiently. While this is true, what they dont tell you is that their clean filter lets dirt through until it traps enough to become efficient! Get the best filtration the first time with AEM BRUTE FORCE intakes and the DRYFLOW Synthetic filter.

All AEM Cold Air Intake systems come with a complete hardware kit and a comprehensive installation instruction guide.

Every AEM Cold Air Intake is either C.A.R.B. exempt or pending C.A.R.B. exemption (50-state legal). All AEM Cold Air Intakes are manufactured and assembled in the U.S.A.
