Exact fit and better quality than the Original
In TX we have heat and humidity that just destroys things. I noticed mine was warping and the foam had cracked which caused a vacuum leak. This one has a stronger neoprene seal that appears it will hold up better than the original. 2mos in and happy so far.

AC Delco OEM Part
Best price, same AC Delco quality part, and it takes only seconds to replace because it’s just that easy. My original had a crack and was covered in oil, so I decided to replace all the hoses and the PCV as well, since it was likely clogged (which it was).

Fit perfect on my 2013 GMC Acadia
I replaced this and it fit perfect. There are great videos on YouTube about replacing and cleaning these PCV breather and valve parts along with the air intake and the throttle body. I had oil in my intake. Watch the videos and get some CRC cleaner.

2012 GMC Acadia
Fit my 2012 gmc acadia. Although it was ever so slightly shorter than the original. Still fit fine. Must have changed the specs since 2012. The connector is a push lock. Pushes ONE way. Fyi
