Attention Non North American Customers

It has been brought to our attention that the North American and Non North American STi have different methods of attaching the fuel hoses to the fuel rails, yet both still use quick disconnects at the firewall side. Thankfully, we cater to both markets and make kits for either application. Please reference the product photos to decide which version you have, then properly select this Model Type from the drop down menu next to the Add to Cart button.
