EZ Lynk Sued By U.S. Government For Selling Vehicle Emissions Defeat Devices

Last November, we reported on a new study from the Environmental Protection Agency, which found that over a half-million modified diesel-powered trucks in the U.S. are emitting high levels of pollutants, many of which are directly linked to respiratory diseases. In recent years, the government has been working to crack down on companies that sell vehicle emissions defeat devices, and now, its latest target is EZ Lynk, a well-known diesel truck tuning company.

According to Reuters, the U.S. Department of Justice filed a complaint against EZ Lynk in the federal court in Manhattan, accusing the company of violating the federal Clean Air Act by selling vehicle emissions defeat devices since 2016. These devices allegedly allow pickups built by Ford, GM, and Ram to run without their emissions systems, which are designed to trap harmful pollutants.

EZ Lynk certainly isn’t the first company to face the wrath of the government, as the EPA levied hefty fines against fellow diesel tuner H&S Performance back in 2013, which ultimately led to the company going out of business. Others have skirted the law for some time now by labeling their products for “off-road use only,” but many who purchase the devices use them on vehicles that travel primarily on public roads.

EZ Lynk’s devices can be plugged into a vehicle’s OBDII port, while the corresponding software is stored in the cloud. Users can buy and install software via their smartphones using an app. According to the court documents, the company “actively encourages” users to utilize their emissions defeating software, including via an official online forum.

“Emissions controls on cars and trucks protect the public from harmful effects of air pollution,” U.S. Attorney Audrey Strauss said in a statement. “EZ Lynk has put the public’s health at risk by manufacturing and selling devices intended to disable those emissions controls.”

    Throw the book at these ‘cheater’ companies. Ford has worked hard to clean up their engines while providing excellent fuel economy and performance. Cheaters do not advance the interests of ICE…. they do hasten the transition to hybrid and BEV technology. Look at VW! Just sayin….

  2. Big FN deal. Hybrids and batteries are for pussies


    Battery powered electric cars.
    Why can’t they install twin altenators to
    Charge up the battery pack while the vehicle is going down the road.
    Personally I like gas run cars over the electric, I am old school.

    These type of aftermarket ‘updates’ have been available for years. Changing the ‘chip’ has resulted in huge power increases on gas engines. Modifying vehicles for MORE POWER has gone on since the first cars were produced and I doubt that will ever stop. Don’t forget the basis rule – it isn’t cheating if you don’t get caught!! LOL

    Biden’s friends may start to require mfgs to build their computer system in such a way as to defeat the plug in/chip tuners-other than CA, most of the “cheaters” are in fly over country.
