Subaru 13211AA110 Exhaust Valve Stem Seal

The Subaru 13211AA110 is a genuine OEM exhaust valve stem seal designed to maintain proper valve train operation and prevent oil consumption in Subaru engines. This critical component creates a tight seal around the exhaust valve stem, preventing engine oil from entering the combustion chamber through the valve guide.

Key Features:

• Genuine Subaru OEM part ensuring exact fitment and quality
• Heat-resistant rubber compound designed for high exhaust temperatures
• Prevents oil leakage past the valve stem into the combustion chamber
• Helps maintain proper oil consumption and reduces smoking
• Direct replacement for worn or damaged valve seals

Valve stem seals are essential wear items that should be replaced during valve train service or cylinder head work. Worn valve seals can cause increased oil consumption, blue exhaust smoke on startup, and carbon buildup on valves. This genuine Subaru seal ensures reliable performance and proper engine operation.
