These are easy to install
I did mine several months ago. There are two tabs on the bottom about a half inch in from each side. Protect your hood with a cloth and pry up gently at each tab and they pop right out. The new intakes are hard plastic at the front but soft rubber at the back and slide right in from the outside. You then just reach a finger in from the inside of the hood and pull them through until the rubber locks into place.
