MAZDASPEED Cold Air Intake Filter Assembly For MAZDASPEED 3
The MAZDASPEED Cold Air Intake features a mandrel-bent 6061 aluminum inlet pipe for durability and light weight. Each MAZDASPEED 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.
Bring cold air from outside the engine compartment into the engine through mandrel bent 2.75" diameter, polished and powder coated aluminum tubing. The intake system is designed for improved engine breathing, while re-using the stock MAF sensor. The kit utilizes the latest in dry filter technology.
The MAZDASPEED Cold Air Intake features a revolutionary DRYFLOW filter. 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!
MAZDASPEED Cold Air Intake systems come with a complete hardware kit and a comprehensive installation instruction guide.
Every MAZDASPEED Cold Air Intake is either C.A.R.B. exempt or pending C.A.R.B. exemption (50-state legal). All MAZDASPEED Cold Air Intakes are manufactured and assembled in the U.S.A.
