Emissions Compliance (CARB)

Daytona Twin Tec – CARB EO Numbers: 

Notice to Daytona Twin Tec Customers in California

California regulates automotive aftermarket parts that have the potential to impact emissions. In many cases, the sale and use of emissions related aftermarket parts on motor vehicles is prohibited unless it is either a “Replacement Part” as defined by California or the specific application has been granted an exemption as reflected in an Executive Order (“EO Part.”).

Exempted parts are add-on or modified parts that have undergone an ARB engineering evaluation. If the part or modification is shown to not increase vehicle emissions, it is granted an exemption to emission control system anti-tampering laws. This exemption is called an Executive Order (EO) and allows the modification to be installed on specific emission controlled vehicles. Every Executive Order part or modification has an assigned number that can be verified on the ARB website.  https://ww2.arb.ca.gov/applications/aftermarket-parts-database

NOTE: Some Daytona Twin Tec products are currently sold as “Competition Use Only” or Off Road Use Only” in the state of California.

The California Air Resources Board (ARB) regulates aftermarket parts and has created regulations that essentially place all emissions related aftermarket parts into three categories:

  • Replacement Parts
    “Replacement Part” means any aftermarket part intended to replace an original equipment emissions-related part and which is functionally identical to the original equipment part in all respects which in any way affect emissions (including durability), or a consolidated part. These parts are appropriate for sale and use on motor vehicles used on or off the public highways
  • Add-on or Modified Parts (exemption required Executive Order (E.O.) Parts)
    “Executive Order Parts” are aftermarket parts that ARB has evaluated and determined do not adversely impact emissions, and thereby are granted an Executive Order (EO), which allows the part to be sold and used on specified (make/model/year specific) motor vehicles. Any aftermarket part or system that replaces or otherwise impacts emission control equipment, requires an EO to be sold and used on or off a public highway.
  • Competition Use Only Parts
    “Competition Use Only Parts” may only be sold or used on motor vehicles used in closed course competition. They may not be sold or used on any vehicle that is used on or off the public highways. Competition Use Only Parts are aftermarket parts that replace, modify, or alter any required emission control device, such as a catalytic converter, oxygen sensor, camshaft, or fuel control module.
