KO Motorsport will not perform emission deletes on any vehicle, regardless of use or application. The laws in place both federally and in NY impose fines on business owners and vehicle owners for the tampering with, or deleting of, any emissions part or system.

The EPA has recently announced new Priorities for Enforcement and Compliance Assurance for Fiscal Years 2020 - 2023, which includes:


  • Stopping Aftermarket Defeat Devices for Vehicles and Engines – This NCI will focus on stopping the manufacture, sale, and installation of aftermarket defeat devices on vehicles and engines used on public roads as well as on nonroad vehicles and engines. Illegally-modified vehicles and engines contribute substantial excess pollution that harms public health and impedes efforts by the EPA, tribes, states and local agencies to plan for and attain air quality standards.
