AEM provides a cold air intake system that is recommendable to any enthusiast because of their reputable work over the years of staying on top of the market. The system provides increased airflow that is engineered for all-out performance and awesome aesthetics to the engine bay with its stylish designs.

The gray AEM cold air intake for the BMW F3X 335/435 N55 is a performance cold air intake system producing more HP and torque over the restrictive factory intake. This air intake system was designed, tuned, and dyno-tested to fit specific BMW F3X 335/435 N55 models. The air filter is relocated to the driver-side wheel well which is designed to reduce intake air temperature and increase horsepower.

The air filter is placed into an open-bottom AEM air box which is designed to protect the air intake system from engine bay heat while also helping to produce a more aggressive engine sound during acceleration. The air intake tube is made from lightweight, yet durable, high-density polyethylene and is aerodynamically engineered to flow air freely into the engine's turbo inlet. The tapered cylinder-shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty.
