Shipping policy

Updated October 16, 2026.

Shipping availability and charges

We currently ship to eligible United States addresses. Available shipping methods and charges are shown at checkout. Product-specific destination restrictions apply; a checkout shipping option does not establish that a performance part is legal for your vehicle or use.

Processing and delivery estimates

In-stock orders are typically processed within 1–2 business days. Typical transit is 3–7 business days after shipment, depending on the destination and selected service. These are estimates, not delivery guarantees, and do not include supplier backorders, weekends, holidays or carrier delays.

Backorders and delayed shipments

Availability and supplier estimates shown on the product page take precedence over the normal in-stock timeline. Motorcraft SP589 plugs are available to order on supplier backorder, with estimated supplier shipment November 11, 2026. This is not a guaranteed customer delivery date. We will provide an updated shipping estimate if the supplier schedule changes.

If we cannot meet a stated shipment time, we will notify you and offer the choice to consent to the delay or cancel for a full, prompt refund as required by law. Contact justin.t@acceleronautomotive.com to ask about an unshipped order or request cancellation.

Tracking and delivery issues

We send tracking information when your order ships. Carrier tracking may not update until the first scan. For a missing, damaged or incorrectly delivered package, contact us promptly so we can investigate with the carrier. Keep packaging and photos where available.

Returns

Request eligible returns within 14 days of delivery. See our Refund Policy for conditions, exceptions, return shipping costs and refund timing.
