OEM replacement
This is a difficult part to change the old one will break upon removal it is a press fit and without specific GM removal tool you just need to force it out. The installation is easy as can just push in and it will lock in place with side tabs.

GM genuine...
Very nice stock replacement part. Be very careful installing if you're a DIY person... Otherwise, have it done by a professional. Smoothed out our 2017 chevrolet cruze rough idle. This valve being bad can also trigger the dreaded proverbial P1101 DTC.... Thank you, part came quickly and without damage. Happy wrencher!!!!

Irritating
Broke instantly on install. Very frustrating because the hose for this piece dosent even exist online And they won't give me a refund for this plastic garbage that i NEED to start my vehicle. I'm constantly fighting everything auto wise. Everything is made to break on you And steal all of your hard earned money.

Great price for OEM product
Got this for my daughter's car but was not able to install without removing the manifold cover. Gave it to dealership who installed it as part of other work being done. Saved me time and headache.
