SURE Aeros ID400 MAF Housing

Aeros [air-ose, air-ohs]. This is the grandfather of all Aeros intake systems and features the largest 4.00in MAF housing that SURE has to currently offer. This allows for optimal air flow and increased power when paired with the correct tune. This is only the MAF housing and does not include a filter, intake hose, triangle bracket or rubber isolator.

MAF Sensor Housing

MAF stands for mass air flow, which is a very important sensor that meters air entering your Mazda. The new larger MAF housing allows for more air travel and allows for more power on your Mazdaspeed with the correct tune. Proper design is crucial for accurate air metering. Our AEROS™ MAF housing is machined from 6061 aluminum.


The entire MAF housing assembly is put through the anodizing process. This not only makes for an beautiful finish, but more importantly adds corrosion resistance. Anodizing ensures a strong, smooth finish that stands up against corrosion no matter what the driving conditions.
