Diesel Emissions Testing

Boulder Dyno Testing offers diesel emissions testing service for most light duty vehicles (vehicles with a GVWR of less than 14,000 lbs).

Testing is done by APPOINTMENT ONLY

*At this time we do not test gasoline powered vehicles.
Visit Air Care Colorado's website for gasoline emissions testing info.


*We cannot test vehicles with metal-studded snow-tires on the drive axle, as they damage the testing equipment.

*Unfortunately at this time we cannot test AWD vehicles
