Detailed Product Overview

The IV808 is an engine intake valve designed for the internal combustion process, opening at the correct camshaft interval to admit the air-fuel charge into the combustion chamber. Its nitride-coated finish helps protect the valve surface under heat and mechanical stress, while the specified 39.4 mm head diameter, 7 mm stem diameter, and 91.6 mm overall length support accurate fitment in the listed Volkswagen and Audi engines. If you are replacing a worn intake valve during cylinder head repair, IV808 provides the dimensional consistency needed for proper sealing and valve train operation.

This part number, IV808, is used across multiple 1993-2006 Volkswagen and 1995-1998 Audi applications, including Volkswagen Golf and Audi A4 Quattro service work where intake valve wear, sealing loss, or heat-related damage has occurred.
