that red part in the last picture look like that spacer, it's used for joining two rubber hoses together
The silver pipe in my picture is the cold air feed to the air filter. I plugged into the bottom of the filter then I ran it into the front bumper through a gap I found when the bumper was off. There's a big void (empty space) inside the bumper that it can suck cold air from.
To help this I cut out the fake intake in the front bumper next to the fog light to allow more air in. You could even sit the pipe behind this opening if you wanted even more cold air
