## Description

AEM Air Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested to fit specific cars and trucks. These air intakes usually include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. Most AEM intake systems use mandrel-bent aluminum intake tubes, powder coated heat shields, and high quality hardware designed to reduce restriction and reduce intake temperature. The design and components of each intake system vary so consult the installation instructions for more information on the contents of each part number. AEM manufactures a variety of intake kit styles including short ram intakes, cold air intakes, dual-chamber intakes, Brute Force intakes for trucks and SUV's, and Brute Force HD intakes for diesel applications.

## Customer Reviews

### ⭐⭐⭐⭐ Great deal, arrived damaged, but easily fixable.
*by J***N on December 16, 2023*

If your AEM intake arrives damaged, you can easily fix it. Head to your local AutoZone and borrow the OEMTOOLS 2-1/8 in. to 3-7/8 in. Tailpipe Expander. Hand tighten the expander into the pipe and then use a ratchet to expand and round the pipe out. I had to readjust the expander a few times to get the pipe as round as possible. It isn’t perfect, but I couldn’t pass up on the deal I got if I returned the intake.

### ⭐ AEM makes installing a cold air intake easier said than done.
*by M***Y on September 22, 2022*

arrived damaged/bent, didn't align with screw on Honda Prelude 1999. AEM, please fix your product and the quality control.

### ⭐⭐⭐⭐ Works great
*by N***M on December 3, 2021*

The intake definitely helps get more air and especially feels more responsive in colder weather. The installation process was a hassle because the mount for the intake did not line up with the mount on the car. Otherwise this product works great.
