I have seen tons of Stillen intake installs but had been looking for nismo specific portions as related to the "plates" on the front bumper structure. Had to do a little minor surgery to get the fitment where I was satisfied.
I didn't remove the full plate on both sides just the portion that connects up with the upper bracket\structure. This led to moving the horn on the right side and strapping the cabling to the center structure. The horn was easy. Take the bracket off of the plate you remove and use the same bolt hole at the top where the plate connected. A hammer and chisel take the rivet out in about three hits and a Dremel cutting wheel will cut the plate like butter in less than a minute. Also had to slightly bend out the outer tabs on the upper support bracket that hold the hood release cable.
Hope this will answer some of the questions that others might have.
