Purge the Air

FAST Nitrous Purge Kits are an indispensable component for anyone running a nitrous oxide system, offering both performance gains and crucial safety benefits. By purging vapor and unwanted air from the feed lines, this system ensures a block of dense, liquid nitrous arrives instantly at the solenoid. This eliminates hesitation or lean spikes during activation, improving throttle response and maximizing horsepower with every hit. Designed by FAST, manufacturers with established expertise in EFI and power-adder components, these purge kits reflect high build quality and engineering reliability for racers or performance enthusiasts who demand consistent, repeatable launches and horsepower.
