Emissions Services in Wheat Ridge, CO

Performance Wise provides light duty diesel emissions testing on most light duty cars and trucks up to 14,000lbs gross vehicle weight, we cannot test vehicles over 14,001 GVWR or with stacks or AWD (all wheel drive vehicles / full time 4 wheel drive).

Vehicles that have a check engine light on will fail as well as vehicles that have had emissions components deleted or tampered with. For example missing EGR valves and EGR coolers / catalytic converters and deleted DPF systems (Diesel Particulate Filter).

No appointments = first come first served, each test takes about 15 minutes and cost is $60 pass or fail. Testing is done Monday thru Friday 8am to 4:15pm

Performance Wise is not responsible for any mechanical damage that might occur during testing, vehicles are tested using a dynometer which simulates heavy load driving. It is your responsibility to make sure your vehicle is in good, safe running condition and free of fluid leaks. If we feel that your vehicle is not safe we will not test it.
Diesel Emission Testing is required for the state of Colorado. No appointment Needed. Hours 8:15am - 4:15pm Visit our shop today in Wheat Ridge, CO at 720-898-0808.
