The GKTECH Blow Off Valve return blocker fits all S13, S14 and S15's, R33 (GTS-T) and R34's (GT-T) and is to be used on the intake pipe when the standard blow off valve is removed. If the hole left from removing the blow off valve isn't removed, air will get sucked into the intake after the air flow meter and the car will run very rough.
