Restore Engine Efficiency

If you are experiencing oil consumption or blue smoke from your exhaust, it may be time to replace your valve stem seals. The GSC Power Division Valve Stem Seal Set for the Mitsubishi 4B11T engine is designed to provide a superior seal, preventing oil from entering the combustion chamber and ensuring your engine runs at peak efficiency.

Technical Specifications:

• Engine Fitment: Designed for the Mitsubishi 4B11T engine (Evo X).
• Quantity: Set of 16 seals, covering all intake and exhaust valves.
• Material: High-temperature Viton construction for long-lasting performance under boost.
• Fitment: Fits 2006-2015 Mitsubishi Lancer Evolution and Ralliart models.

These seals are a critical component of any cylinder head refresh or engine build. By maintaining a tight seal around the valve stems, you reduce oil burning and carbon buildup on your valves, which can lead to power loss over time. GSC Power Division utilizes advanced materials to ensure these seals remain flexible and effective even under the intense heat cycles of a turbocharged engine. Whether you are performing a routine maintenance job or a full engine overhaul, these seals are the perfect choice for your Mitsubishi. Find all your essential engine seals and gaskets at GGCRACING.
