Give your turbo an extra boost and eliminate boost lag with ZEX turbo nitrous systems! Specifically designed for turbo applications, these nitrous systems include a fully adjustable boost switch. This switch allows you to spray a small shot of nitrous, helping to instantly spool-up your turbo. Once a certain level of turbo boost is reached, the switch deactivates, shutting off the nitrous. ZEX turbo nitrous systems are adjustable from 25 to 75 hp.
