NOW AVAILABLE! 2021 Mitchell 1 Emission Control Application Guide

As you probably already know, many states require motorists to get a smog test before they’re allowed to get their vehicle registration. California, for example, requires a vehicle to be smogged every two years.  With the growing number of motorists on the road, this means there is a constant demand for smog emission test services.

Because of the dynamic nature of the automotive industry, it is important to stay up to date with the most current emission system information when those customers enter your shop. That is why we publish an annual Emission Control Application Guide (18ECAT) information. Inside you’ll find vehicle-specific emission system information for the newest vehicles on the market.

As engine controls become more complex with other vehicle systems, the new Emission Control Application Guide can help shops cut through the complexity. For repair shops that use the online repair information in ProDemand, this printed companion guide is a great resource to help stay in compliance with state emission standards.

You will find lots of new specific content features.

Including coverage on:

• Emission Application Tables
• Engine Displacement Conversion Charts

• Approximately 40 years of Domestic and Imported Basic Ignition Timing

Added specifications with regards to:
