1.8T 5V Exhaust Valves (Set of 8)

The Supertech Black Nitride Exhaust Valve Set, part number AEVN-1103-8, is engineered for enhanced performance in Audi and Volkswagen 1.8T 5V engines. Each valve in this set of eight is constructed from high-strength Stainless Steel 23-8N, offering superior durability and resistance to high temperatures. The one-piece forged design ensures robustness, while features like a back-cut angle, undercut stem, and a magnetic friction-welded wafer contribute to improved flow rates and better sealing capabilities. The black nitride coating provides superior surface hardness, which helps maintain core ductility and reduces carbon buildup, ultimately leading to improved engine durability and reduced friction. The "Superfinish" valve stem finish further minimizes friction, contributing to overall engine efficiency. This set is specifically designed for the following applications: 1997-1999 Audi A4, 1997-2000 Audi A4 Quattro, 2000-2002 Audi A6 Quattro, 2001-2002 Audi Allroad Quattro, 2000-2002 Audi S4, and 1998-1999 Volkswagen Passat. Please note that due to the nature of performance engine components, these parts are sold without any express or implied warranty of merchantability or fitness for a particular purpose.
