This repair fixed the problem by replacing the intake boot but the individual intake runner gaskets were not an exact fit. Had to use an adhesive to hold them in place. Seems to be okay and do not have any intake leak so far.

Great Product that fit as advertised
I am always apprehensive about ordering car parts online as I have had sites that claim the part fits my car only to find out it does not when I receive it. This wastes so much in receiving and returning. However, I had to order this part my local stores didn’t carry the part. It fit perfectly in my 03 Deville and even came with gaskets that fit my intake. I am impressed and will order from 1a if I have to go to the web again for parts.
