## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect Fit
*by R***2 on July 9, 2022*

This oem part was a perfect fit for my 2010 Cadillac CTS!

### ⭐⭐⭐⭐⭐ Fits my 2009 Cadillac CTS
*by J***M on March 16, 2022*

Right part; they renamed/renumbered the original GM part from GM 12603359Insulator, Intake Manifold to this 12639254. Hard to tell in the pics so I uploaded a few - it’s all one thickness not a chunk of foam.
