Due to varying state, federal, and provincial regulations, specific emission control equipment may vary by area of sale. The U.S. emission equipment is divided into two categories: California and 49 State (or Federal). In this section, the term "California'' applies only to cars originally built to be sold in California. Some California emissions equipment is not shared with equipment installed on cars built to be sold in the other 49 states. Models built to be sold in Canada also have specific emissions equipment, although in many cases the 49 State and Canadian equipment is the same.
