Supertech Mini Cooper N14B16/N18B16 Sodium Filled Inconel Exh Valve - +0.8mm OS - Single (D/S Only)

This listing is for a single Supertech exhaust valve, specifically designed for Mini Cooper models with N14B16 or N18B16 engines. It's an oversize valve, measuring 0.8mm larger than stock, and is intended for the exhaust side only. The valve is constructed from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme heat, making it ideal for demanding engine conditions.

Sodium filling is incorporated into the valve stem. This advanced cooling feature helps dissipate heat away from the valve face and stem, which is crucial for maintaining valve integrity under high operating temperatures. The Inconel material combined with sodium cooling offers improved durability and performance compared to standard exhaust valves, especially in performance-oriented or heavily used engines.
