Any IHRA or NHRA sanctioned track will require these blow-off caps in all classes when you run with nitrous oxide. These are safety devices that fit on the bottle. If your nitrous system creates too much pressure, one of these caps will allow it to bleed off through the vent tube, which exits outside the vehicle.
