For international shipments, make sure your address information is accurate. CS Performance assumes no liability once package leaves the United States. Please be sure your country is accepting packages from the US and you are aware of any duties or taxes your country may require upon package arrival.

Core Returns are completely optional and not required. When you order a set of fuel injectors from us, eligible part numbers will have a paper slip inside the shipping box. This paper slip will have all of the additional information regarding the return of your old cores for a varying price (depending on the part number you are looking to send in).

If your old cores are not eligible to be returned, you will not receive this paper slip within the shipping box, and no further action is required.

Thank you for your time and business, we appreciate it greatly!
