The Anti-Stall kit is designed for those who have Mass Air Flow equiped forced induction vehicles and want to use the Synchronic BOV to vent to atmosphere instead of re-circulating the discharged air.
The Anti-Stall Kit is a cap that fits over the discharge of the BOV. The cap is attached to the BOV by a long screw and a spring. When the BOV discharges, it will blow the cap open and release the discharge air. When the BOV has finished discharging the air, the spring will pull the cap shut, hence the BOV will not be blowing out metered air and causing the MAF car to stall or idle rough.
The kit comes with the following parts and should be installed in this order:
Bolt -> Spring -> Washer -> O-ring -> Anti Stall Cap
Do not over tighten the bolt onto the valve as it may cause heavy load on the spring and preventing the cap to properly open during discharge.
***It is recommended to always re-circulate the BOV discharge air for best vehicle performance and drivability.***
