Default home-brew ram air box

finally got my new hood painted and installed and couldnt stand driving around with a non-functional ram air hood, so me and my buddy went to the local lowes and picked up some stuff and this is where it ended up.


used the bottom of the stock air box as a starting point and built everything up from there using hvac stuff and some aluminum sheet metal.

Nice job with all that fabbing needed.
couple questions.
Why the air filter that pulls hot engine heat in? Is it a straight through filter from the inside or is there filter element inside?
Are you using any filters like K&N for drop in?

I don't see how that would work correctly with that filter half way down the tube. Ram air works by forcing air into the intake and that would crate pressure. Having a open filter like that half way through the pressure would just release out that filter. Also if you didn't seal the hole in the factory box it would do the same thing.

A for effort, and the hood looks great, but I think you could do the ram air better.

If your keeping your current setup I hope you closed the hole in the front of the stock air box, we can't tell from the pics, but you gotta git rid of the filter half way through. Any pressure your building is definitely being released right there.

I would suggest this.....

Using PVC, make a pipe that uses the stock opening in the front of the air box as the output of the ram air box towards your throttle body. Replace the adapter you made with another, obviously with out that hole in it. Put a drop in filter in the box.

So what will happen is, air flows into your hood, get pushed into the adapter you made down into the air box, gets filtered by the drop in, gets pushed out the front of the air box where your pvc intake takes it to your throttle.

And make sure you weld or jb weld all the edges. If there is anywhere for pressure to escape, it will.
