ATS Diesel Performance ("ATS") sells replacement parts designed to improve a diesel engine's efficiency and reliability. Some states, specifically California, have strict regulations applicable to parts that you may legally use on your diesel truck. Be sure to review applicable municipal, state, and federal rules before you purchase and install an ATS product to make sure you are in compliance.
ATS also designs and manufactures certain parts for off-road and race use only. These parts are not intended for sale in any state, including California, where the items do not comply with local rules.
