Brands that ship from international locations such as Milltek typically take between 4-7 business days to be delivered.

Customers either pay $9.99 or nothing for shipping - no surprises at checkout! The majority of orders are delivered within 1-3 business days using the free shipping option, however some orders can take up to 5 business days depending on your location.

Our return policy allows customers to return most orders within 30 days (7 days for AutoTecknic parts).
