Apex Gaskets AVS4013 Engine Valve Stem Seal Set

The Apex Gaskets AVS4013 is a replacement engine valve stem seal set designed to restore proper oil control at the valve guides and prevent oil from entering the combustion chamber.

• Engineered to meet or exceed OEM specifications for a precise, leak-free fit
• Manufactured from heat-resistant, durable elastomer compounds to withstand high engine temperatures
• Provides consistent oil metering at the valve stem for optimal lubrication without excess oil consumption
• Covers domestic, Japanese, Korean, and popular European engine applications
• Backed by Apex's limited manufacturer warranty
