AEM Performance Cold Air Intake Systems produce horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Chevrolet Cruze models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The air intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the mass air sensor. 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). This air intake system is easy to install with commonly available tools. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Installation was simple took a lil over an hour. I can feel the difference.

I installed this intake in my 2017 Malibu LS. I originally received a pipe that had the MAF sensor upside-down - luckily, AEM was on top of it and not only overnighted a pipe from California that was correct, but after I sent pictures, they told me they would make sure the pipe issue was fixed and they would work on heat shields fitting properly without cutting. Which leads to the fact that he heat shield was too tall - with metal cutters I trimmed about 1.5in off of it and it fit perfectly. The sound is better, especially the blow-off, and I can tell it has a little more power with a little more throttle response. Also, note that it is now MUCH easier to replace your headlights - before I had to take the whole intake box out completely to change my passenger-side headlight. Now, I have much easier access. Honestly, it should only take about 45 min to install, including cutting the heat shield. I would personally highly recommend this for the sound, airflow, slight power increase, and easier access where the intake is.

Bought this as a Christmas gift to myself. Very easy to install took maybe 15 minutes, sounds amazing and looks great. The car does feel like it has better acceleration. Thanks AEM for a great product.
