Overview
Nitrous Express Blow-Off Caps
Any IHRA or NHRA-sanctioned track will require these Nitrous Express 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 of the vehicle.
