Supertech Alfa Romeo Q4-16V Turbo 28.4x6.97x125.5mm Tapered Inconel Exhaust Valve - Set of 8

This set includes eight Supertech tapered exhaust valves, each measuring 28.4mm in diameter at the head, 6.97mm for the stem, and a total length of 125.5mm. These valves are specifically made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures, making them a solid choice for turbocharged engines where exhaust gas temperatures can get very high.

Using Inconel for exhaust valves helps prevent warping and burning under the intense heat and pressure found in performance turbocharged applications. The tapered design can also contribute to improved flow characteristics as exhaust gases exit the cylinder. These valves are a well-built component for rebuilding or upgrading the cylinder head on your Alfa Romeo Q4-16V Turbo engine, offering durability where it matters most.
