Do not even think about it.

Don't buy that. Despite the claims, it is impossible to install 2 liters on the Mazda 3. Doesn't fit, doesn't even come close. Dear garbage. Stay away.

Pros
  • Great price
Cons
  • Vulgarity

This makes driving fun again!

This is great! Everything fit perfectly and was assembled in about 30 minutes. On my 2017 Mazda 3 2.0 it sounds very nice and raspy at low to mid RPM. Not as loud as expected in the upper rpm range.

Pros
  • GOLS certificate
Cons
  • The list is getting long.

Easy installation, completed in about 45 minutes

Easy installation, completed in about 45 minutes. Makes a pleasant hoarse sound, the car picks up speed more easily at low and medium speeds. For those who say they can't mount it, you MUST install the heat shield and factory shovel at the same time (Step F in the instructions). The location of the air box on these vehicles is limited so you need to keep that in mind. If everything is done correctly, then everything is fine.

Pros
  • Air intake
Cons
  • There are new competitors

HEAT SHIELD NOT MOUNTED

Heat Shield does not fit the standard inlet which the owner's manual says should be reused. Why?1. The heat shield cutout differs from the factory cutout2. The heat shield hole is 9cm smaller than the factory 10cm hole. Despite what I've already told them, AEM doesn't want to double check their installation, whether it's a 2014, 2015, 2016 or 2017 Japanese-made Mazda 3 BM 2.0 liters (since they all have the same intake) means it won't fit. Bad customer service.

Pros
  • Automotive
Cons
  • Small Parts

Great product - Filter

According to the owner's manual you only get 1hp but you get more throttle response and a bit more noise under the hood (hard to tell as I have an exhaust). . The cleaner looks under the hood. All parts are made of very good metals. The filter is easier to clean compared to the OEM. Disadvantages. I couldn't save my life by sticking a regular noise resonator on a cold air intake! and I've tried everything! but it would actually restrict airflow and defeat the purpose of this product lol it…

Pros
  • Filter
Cons
  • unreliable
