HOW TO INSTALL YOUR BOV
Please check that the following items have been provided in your Subaru Vee Port Pro kit.
Quantity Description Use
1 Subaru Vee Port Pro BOV Model Specific blow off valve
1 34mm Blanking plug To blank off the standard return pipe
1 Gasket To seal the BOV to the intercooler pipe
1. Remove the standard BOV from the intercooler by removing the two bolts. Disconnect the vacuum line to the top of the standard
BOV.
2.
Using pliers, carefully clamp onto the spring clamp on the plumb back hose and pull the BOV off the hose. Then carefully install the
provided 34mm blanking plug into the plumb back hose and secure it with the standard spring clamp.
3.
Install the Vee Port Pro using the standard screws. Do not forget to install the provided gasket in between the BOV flange and the
intercooler flange. Re-fit the standard vacuum tube to the BOV.
4.
Start the car and check for leaks.
ADJUSTING YOUR BOV
Each BOV needs to be adjusted to suit the vehicle it is being mounted on. The aim of the adjustment on Vee Port Pro, Supersonic and
Dual port is to make sure that the piston is hard closed at idle and that the piston closes fast enough to minimise backfiring and not stall
the engine. Plumb back BOV’s are equipped with a spring which are designed to keep the piston open at engine idle and hence the cap
can be left in the middle position.
Adjustment to the BOV is made by rotating the cap. To increase the spring force on the piston, rotate the cap clockwise in the direction
of hard as marked on the top of the cap. To decrease the spring force on the piston, rotate the cap anticlockwise in the direction of soft
as marked on the top of the cap - CAUTION - Do not rotate the cap beyond the first O-Ring indicator groove.

Start with the BOV cap at the maximum soft position (The indicator O-Ring should be completely covered by the edge of the cap)
 With the engine at idle the exhaust port should be closed off by the piston – the piston should be hard against the seat and not
floating or moving

Free rev the engine and back off quickly, the engine should return to normal idle speed – if the engine drops below idle or stalls
increase the spring tension by one turn

Repeat this process until the engine free revs and returns to normal idle speed

Test drive the car and ensure that when decelerating or changing gears that the engine has minimal backfiring and no stalling. If
backfiring is excessive or stalling is noticed then check all connections made during the installation, otherwise increase the spring
tension
