The pic pretty much explains itself below. I used two (3" x 5") 3/4" pieces of pressure treated plywood and one 3" x 5" piece on the backside painted black. The plywood pieces are mounted on each side of the intake horn and I used four 5" long bolts to tie the plywood together on each side of the intake horn.
I used blue loctite on all nuts because I'm excessive like that
. The three nuts that were used to mount the Amsoil bracket to the plywood are hidden. On the second piece of plywood that is behind the piece the Amsoil bracket is mounted to I used a wood bit and countersunk three 3/4" holes so that the nuts would fit in the holes and the two pieces of plywood in front would mount flush to one another.
Once the bolts are tightened down the plywood WILL NOT MOVE. I wanted my Amsoil bypass filter under my hood so that's why I went to the trouble to do this. By the way, I just purchased the BK-203 Amsoil bracket and used my own hoses and fittings. The mount is a heckuva lot cheaper than buying the entire BMK-11 kit from Amsoil, but either one will work just fine.
