The AEM 21-754DS features an aerodynamically engineered intake tube formed out of high-density, low-restriction polyethylene that produces superior airflow to the 335i's turbo.
Widely respected and held in high esteem by the motoring public and the auto resale industry, BMW's 3 Series has provided a top-notch sport sedan driving experience over five generations. When BMW completely revised the 3 Series sedan in 2012, it was a highly scrutinized change, but everyone came away smiling. The sixth-gen result was a bigger car with a redesigned exterior and more interior space, but, thanks to liberal use of aluminum in the suspension system, lighter than its predecessor. Plus, the newly introduced Driving Dynamics Control, (four transmission modes that let the driver select the throttle response, steering effort, and shift patterns of the automatic transmission) for all models appealed to drivers and provided increased engine efficiency and fuel economy. An optional eight-speed automatic transmission and an auto stop/start system comprised the changes to the powertrain, and BMW was again leading popularity charts. AEM realized this and created the new 21-754DS air intake system for the 2012-2015 BMW 335i.
The oversized AEM Dryflow synthetic air filter is mounted inside an open-bottom air box that protects the intake system from heat while helping to produce that aggressive 335is-like note on acceleration.
At the top of the range is the 335i as a sedan or coupe with a 3.0-liter inline six-cylinder turbocharged engine producing 300 hp and 300 lb-ft of torque. This power plant has carried over successfully from 2012 through 2015. The 335i is the epitome of step-up vehicles for those engaged with the marque at 320 and 328 levels, or the driver looking for the next big thing for daily driving and weekend touring.
While already a great performer with 0-60 acceleration at about 5.4 seconds, 60-0 braking at about 117 ft., and respectable fuel economy of 25 mpg combined for the sedan (with automatic trans) and 22 combined for the coupe (manual), you can take the 335i to another level with increased horsepower and torque. The way to accomplish this levitation for the 2012-2015 335i sedan and 2013 335i coupe is with the new AEM 21-754DS cold air intake system, which, in dynomometer testing on a 2012 sedan showed an estimated gain of 12 horsepower and 20 foot-pounds of torque at 3200 rpm. You could really go places with those numbers, and the car will have superior airflow and filtration, while sounding very much like their sporty 335is sibling.
Designed and engineered to replace the factory intake housing, air is brought into the system through an oversized red AEM Dryflow synthetic, washable air filter fitted to an open-bottom AEM air box. The replacement air box not only protects the intake system from engine bay heat but helps to produce that aggressive 335is-like note on acceleration.
The 21-754DS system specifically accommodates the 335i's factory emissions control devices, including the mass airflow sensor. The aerodynamically engineered intake tube is formed out of high-density polyethylene and creates a superior flow of air into the engine’s turbo inlet after it has passed through the cylindrical AEM Dryflow filter.
AEM cold air intake systems are very straightforward to install with no special tools required.
There is also economy built into this system in that the synthetic, oil-free air filter can be cleaned and re-used. Intended to last up to 100,000 miles before a service (depending on driving conditions or owner preference), the filter is easily removed, cleaned with AEM 1-1000 Air Filter Cleaner, rinsed, dried, and replaced.
The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty.
