Review on Cold Intake Super Powerstroke Diesel by Tim Lee

This automotive filter is a complete waste of money. Through trial and error, I found that it doesn't make any difference in the performance of my vehicle, and the installation process was a nightmare. The only pro is that it's cheap, but you truly get what you pay for. The cons are numerous - it doesn't provide the power boost that it claims to, it doesn't fit snugly in place, and it worsens fuel efficiency. Do yourself a favor and steer clear of this product.
