Powerful Upgrade for Car Air Filter

Based on my experience, this car air filter is a game changer.The installation process was easy and straightforward, and the increase in horsepower and torque was noticeable right away. The filter also looks great under the hood adding a sleek and sporty touch. However, it does come at a higher price point compared to some other options on the market..

Pros
  • Increased horsepower and torque, easy installation, sleek design.
Cons
  • Higher price point.

Disappointing performance for a premium filter

The AEM Cold Intake System may have a sleek design and promise improved airflow, but in reality, the difference in performance is negligible .Based on my observations, the installation process was tedious and the promised horsepower boost was nonexistent. The only plus is the potential slight increase in fuel efficiency. However, for the premium price I expected better results..

Pros
  • Potential slight increase in fuel efficiency
Cons
  • Minimal performance improvement for the cost.

Ehh not worth it.

The product works, I bought it together with BOV and installed it together. The cold air intake fits but does not fit my 2018 VW Tiguan. My model doesn't have a way to screw it on, so it just bounces around. I'm going to take some sikaflex and glue it to the mount so it can't move. Otherwise this is a good product. Performance is not particularly increased, just a pleasant sound.
