International Harvester Differential Spacers

The nitrous purge valve was invented to provide consistent and responsive nitrous delivery. By dispelling vapor accumulation in the supply line, a lag-causing factor, the nitrous will consistently arrive at the solenoid; providing on-demand response. For the best response from your nitrous system, International Harvester nitrous purge valves are the way to go.
