ZEX Nitrous' System for Turbo Applications is specifically designed to help spool-up engines equipped with big turbos. This kit has all the same great features as the standard ZEX nitrous wet systems but includes the addition of a fully adjustable boost switch. This innovative switch allows you to spray a small shot of nitrous to help spool-up the turbo, reducing lag. The nitrous will automatically shut off after certain boost level is met. An advanced technology called Active Fuel Control monitors the nitrous bottle pressure and adjusts the kit's fuel enrichment so the vehicle is never too rich or too lean. Additionally, patented electronics that monitor your TPS sensor, the ZEX kit reliably activates only when you go to wide-open throttle.
