## Overview

The AEM 21-754DS Cold Air Intake System is a vehicle-specific, precision-engineered performance upgrade featuring a lightweight 10.58-pound cylindrical design with a sleek brushed finish, crafted by AEM to optimize cold air flow and boost engine efficiency.

## Description

The AEM 21-754DS performance cold air intake system produces 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 BMW 335i 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 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. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass airflow 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). the air intake system is easy to install with commonly available tools and it is backed by AEM's lifetime limited warranty. 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Not disappointed in anyway.
*by O***Z on July 8, 2020*

So very glad I ordered it. Fits, looks, and sounds amazing. Noticeable acceleration change, not much, but feels freer.

### ⭐ I expected better from you AEM, you've lost my business from this one.
*by R***S on April 21, 2024*

The plastic tube constantly changes it's form from the heat in the engine bay, so the filter will not stay on. No I'm not a nube, I know what I'm doing and I promise, this is a fault in their product. On top of all the plastic you have to cut off on the "so called heat shield" I will say, if you Walt sound... but this one BUT expect major issues with it. If it's too late for you, cut the lip off the inside of the filter and push it as far down the tube as you can... it will help but not fix the issue.

### ⭐⭐ Sounds good but can't keep the air cold
*by A***R on August 7, 2022*

It adds a nice sound to the intake, but the included heat shield can't keep the air as cold as the stock airbox. No one should buy this expecting horsepower gains like the description inaccurately claims. However all should be aware that it will reduce power if installed. The stock intake does a better job keeping the air cool. Warmer air means it takes up more space in the engine, hence less power. If you want a cold air intake that sounds better than factory, get one that's mounted far from the engine. If you don't want to do all that work, save your money and don't buy thisEdit: almost forgot, the kit came with 1/3rd of the bolts needed, so I had to go to the hardware store in the middle of the install
