Supertech Subaru H6 31.5x5.45x103.25mm Blk Nitride Dish Exhaust Valve - Single (Drop Ship Only)

If you're rebuilding the top end of your Subaru H6 engine, you'll want to make sure your exhaust valves can handle the heat and pressure. This Supertech exhaust valve is built to be a solid replacement for your stock component. It features a black nitride dish design, which helps improve durability and performance under demanding conditions.

The valve measures 31.5mm in diameter, with a 5.45mm stem and an overall length of 103.25mm. This specific sizing is important for proper fitment and sealing within the cylinder head. The black nitride coating not only adds a layer of protection against wear but also helps with heat dissipation, keeping the valve operating efficiently.
