Supertech Performance VS-VW7I-6 VW/Audi 7mm Polyacrylic Intake Valve Stem Seals

These precision-engineered seals provide superior sealing performance between the intake valve stem and cylinder head, preventing oil from entering the combustion chamber and reducing emissions.

Key Features:

• High-quality polyacrylic construction for superior heat and chemical resistance
• Designed for 7mm intake valve applications on VW/Audi engines
• Reduced outer diameter design ideal for dual valve spring setups
• Guide OD: 9.8mm (0.385") / Seal OD: 13.2mm (0.520")
• Significantly longer service life compared to OEM rubber seals
• Resistant to heat cycles and chemical degradation

These valve stem seals are the ideal solution for engine rebuilds, performance upgrades, or replacement of worn factory seals. The polyacrylic material outperforms conventional rubber seals that become brittle and crack over time due to heat exposure and chemical breakdown. Perfect for street performance builds and race applications, these seals work exceptionally well with upgraded camshafts, valve springs, and performance valves.
