So I finally got my ebay short ram intake for my 2gnt.
I just have a few questions though about the installation.

I removed the intake hose and the airbox first of course. I tried to put the pipe on the tb with a autozone coupler but it didnt fit, so i had to use that rubber PoS. To get it to fit inside the engine bay i had to put the pipe inside the coupler which stretched the coupler kinda in a ugly angle. Also, i had to remove one of the things to the battery barrier to get the pipe to fit. Any tips or suggestions or revisions? I'm almost afraid that the intake isnt gonna last long lol.

Can anyone tell me how they installed their short ram?

And also, do i need a coupler for the K&N? If so im thinkin a 3"-3" coupler maybe?
