Video demonstrating the dangers of dealing with counterfeit Turbos:

Although there are a number of terms in the turbocharger marketplace that fall under the description of non-genuine, it is counterfeit product that proposes the biggest risk to the market, our Authorised Holset Distributors and your customers. A counterfeit product is a fraudulent imitation of a genuine product; designed to deceive the end-user by using identical packaging, logos, trademarks and labels. Counterfeit turbochargers are a growing problem and are believed to have started in China but we are now seeing evidence of counterfeit activity worldwide.

Why is Counterfeit a problem for Cummins Turbo Technologies and our Distributors?

  • Damaging to our brand name
  • Loss of market share
  • ‘Unfair’ competition.

Why is Counterfeit a problem for the end-user?

  • Counterfeit turbochargers do not undergo the same rigorous testing as Holset Turbochargers
  • Counterfeit turbochargers are not made from premium materials designed to sustain the harsh temperatures and environments turbochargers face
  • Counterfeit turbochargers are not matched to the engine to maximise performance
  • This results in poor fuel economy, significantly reduced turbocharger life and ultimately in some cases, personal safety can be at risk.

What to do if you suspect counterfeit activity?

Cummins Turbo Technologies are serious about combating counterfeit activity and work closely with a specialist intellectual property (IP) lawyer firm. Through this collaboration we are monitoring the marketplace to take action against IP infringements and suspected counterfeit activity.

If you come across any trademark infringements or counterfeit activity that involves the Holset Turbochargers brand or Cummins Turbo Technologies’ name, please contact your account manager or email turbomarketing@cummins.com(link sends e-mail) outlining the details including dataplate information, pictures of the product and invoice. The case will then be reviewed and a decision on appropriate action for Cummins Turbo Technologies to take will be made.
