Description

The FAST Manifold Upper Shell is a 78mm throttle body component designed for automotive use. This part is explicitly stated as not being CARB approved, and therefore requires CARB acknowledgement. It is important to note that this product does not come with fitment application data, and customers are advised to verify compatibility manually before purchase. Key specifications include its Part Type as 'automotive', with 'Epa: N/A'. It is also noted as 'Regular Stock: false' and 'Units Per Sku: 1'. The product is also flagged with 'Air Freight Prohibited: false' and 'Ltl Freight Required: false'.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
