The DNU allows an additional Hyper-Sonic nozzle to be mounted in any of our Boost Cooler kits.
It includes a Tee junction piece with our quick-connect fittings, a nozzle holder and a section of hose.
- Bi-Turbo engines (e.g. Audi S4/RS4, Porsche)
- Engines with 2 separate throttle valves (e.g. V8)
- Powerful engines (> 500 hp), where one nozzle alone is not sufficient.
- 2-nozzle installation for combined charge air and combustion chamber cooling (one Boost Cooler nozzle directly downstream of IC-output, another one right in front of the throttle valve resp. intake manifold).
