Diesel Brothers hit with big fine for tampering with truck emissions
Henry “Heavy D” Sparks and “Diesel Dave” Kiley, better known as the Diesel Brothers on the Discovery Channel, have been ordered to pay $848,000 in fines for illegally modifying the emissions control systems of diesel pickups. The Standard-Examiner newspaper in Utah reported that the fines stem from around 400 violations of removing or bypassing particulate filters or catalysts that reduce NOx and soot emissions.
