Automotive Nitrous Oxide System — Engineering Signoff (Vehicle Modification)
Form number: Mod-Plate-N2O
Recreational automotive nitrous oxide injection systems (NOS, ZEX, Nitrous Express) are not directly licensed but the vehicle modification triggers engineering signoff. The bottle is a pressure vessel (typically 10 lb / 4.5 kg) and requires AS 2030.1 retest, secure mounting, blow-off port and fuel-system upgrade compliance — for road registration the engineer issues a mod plate.
