This CNC machined plug and play adapter allows you to mount
single or dual Coolingmist WMI nozzles WITHOUT the expense and headache of removing and
drilling your factory chargepipe. Shaves a ton of time off the Audi S4 WMI
install and best of all is fully reversible. We suggest the CM10 nozzle for
most S4/5 applications. Nozzles not included. Made in the USA.
