Bypass Valve Replacement
The factory bypass valve in my 2012 Buick Regal was sticking open due to increased boost pressure, causing the check engine light to come on. I ordered this bypass valve which fit perfect and so far so good. Doesn't sound any louder then the factory valve and because it was recirculating it did not require additional tuning. The car is back to running great.
