    Boost Control Solenoids

    If you are not hitting your target boost numbers, and you go down the checklist and everything else is okay with the engine such as no boost leaks, maintenance is up to date as far as spark plugs, oil is topped off, and if you have a COBB Accessport and it pulls no codes, then this could be an indication that you have a faulty Boost Control Solenoid. 

    If you have a faulty Boost Control Solenoid, then more than likely you will only be hitting wastegate boost pressure numbers. With that said if you are driving your Subaru WRX and you're only seeing around 7 PSI of peak boost, then you should inspect your factory equipped boost control solenoid. And if you find it to be damaged or not working for whatever reason, don't feel sad. Here at RallySport Direct, we have several boost control solenoids! We have Boost Control Solenoids made from COBB Tuning that will be a 3-Port design that works with the Accessport to stabilize boost pressure more efficiently. Or check out one of the many fine units from Grimmspeed which is a direct plug and play replacement for your factory boost control solenoid that improves on response and spool time. 

    Also, there are great examples from Company 23, and universal units from PERRIN for those of you who need a boost control solenoid to work with a standalone system. And if you're trying to make more boost, check out our great selection of Boost Control Solenoids.
