Finkelstein Thompson LLP is investigating allegations that customers purchasing oil, air, and transmission filters ("Auto Filters") may have been wrongfully overcharged for those filters. If you purchased such a filter, you may have been a victim of this alleged fraud.

Some recently filed class actions allege several automotive part manufacturers entered into a conspiracy to illegally inflate the price of Auto Filters. According to these class actions, the manufacturers in question agreed to fix the prices of Auto Filters by agreeing not to compete against one another on those prices. If proven, these violations might entitle customers of these companies to legal remedies.
