Review on Roush 421642 Cold Intake Focus by Charles Waller

As AN automotive enthusiast, i decided to upgrade my cars air intake system by purchasing this cold air intake.As a result of using this product, I found that my engine was breathing better, resulting in improved horsepower and torque. The installation process was straightforward, and the filter is washable and reusable saving me money in the long run. The only con I can think of is that the increased airflow creates a slight increase in engine noise, but that's a small price to pay for the noticeable improvement in performance..
