Core Charge and "Advanced Exchange" Policy

XtremeFI sells most of its performance throttle bodies and fuel pressure regulators on an exchange basis. We realize that many of you don't want to have your vehicle down while we are modifying your item, therefore we offer "advanced exchange" on most of our products.

This advanced exchange option involves you paying a refundable core charge upfront and we ship a modified throttle body or AFPR from our stock. Once you have received and installed your item, you put your stock part back in the same box and return it within 30 days for a prompt core charge refund. You experience no down time (except for the install time) and have the chance to test your new product before you return your stocker. These prices are subject to change at any time
