The JR.Spec external waste-gate valve features a robust 38mm diameter piston, making it suitable for turbocharged vehicles lacking a waste-gate, such as those equipped with Holset HX35 or KKK27 turbochargers. Its solid construction ensures superior strength and performance, positioning it as a competitive option in its price range.

Crafted from polished stainless steel, the main body of the valve resists deformation, unlike cast iron alternatives. This durability prevents the scission that can lead to turbine or engine damage. Available in a sleek silver finish.
