Supertech Mini Cooper W11B16A 1.6L Supercharged Inconel Exhaust Valve- +1mm OS - Single (D/S Only)

This listing is for a single Supertech Inconel exhaust valve, designed as a +1mm oversize replacement for the driver's side on Mini Cooper models with the W11B16A 1.6L supercharged engine. These valves are made from Inconel, a high-performance alloy known for its exceptional strength and resistance to extreme temperatures and corrosion, making them a solid choice for demanding engine builds.

The Inconel material is crucial for exhaust valves because they operate under intense heat and pressure. This Supertech valve is built to withstand those conditions, helping to maintain proper sealing and engine performance over time. The +1mm oversize dimension means it's slightly larger than the stock valve, which can be beneficial when rebuilding or repairing cylinder heads, especially if the original valve seats have been reconditioned or require a larger valve for optimal sealing.

When rebuilding the top end of your Mini Cooper's W11B16A engine, using high-quality components like these Inconel exhaust valves can make a notable difference in the longevity and performance of your engine. Ensure you have the correct tools and procedures for valve installation, as proper seating and clearance are critical for engine health.
