Original GM turbocharger boost solenoid regulator.  In the GM parts description they call it a Regulator Valve

GM part # 12649146

Your local dealer will charge you $200+ for this and probably won't have it in stock.

I have these in stock.  On hand and will ship by UPS 2nd day Air

These were removed from brand new GM LTG 2.0L engine turbochargers.  Have zero miles on them.  Were removed from new factory turbos as we use an aftermarket performance part on the factory turbo so we do not use these.  This is why we can sell them before wholesale price!  This is cheaper than GM dealerships pay GM for them.  Quantity is limited.  Once they are gone you will never be able to buy them this cheap again!  Unlike all the other sellers who sell these, ours include all the hoses and hose clamps.  Typically the hoses and clamps need to be replaced as they get brittle after time.

This fits the factory turbocharger for the following vehicles:

2013 to 2019 Cadillac ATS 2.0L 

2014 to 2019 Cadillac CTS 2.0L

2016 to 2021 Chevy Camaro 2.0L

2014 to 2020 Chevy Malibu 2.0L

2014-19 Buick Regal 2.0L
