These ESP Motorsport Atmospheric Dump Valves are the ideal replacement for the factory stock recirc valves.
The main issue you will find with many aftermarket dump valves is that because they only have one piston, they tend to come open at idle, resulting in poor running and stalling at junctions. These ESP Motorsport dump valves use a twin piston design which prevents that. We’ve proven them in motorsport applications right up to 2.2 bar of boost.
This dump valve kit include a 33mm neck twin piston motorsport quality dump valve and a 33mm bung for your stock recirc pipe.
The valves are available in:-
Silver, black, titanium,blue and red. Just let us know what colour you’d like in your order comments 🙂
