For those firebirds not blessed with the ram air hood i made this write up.

Tools:
1) Dremel saw or cutting tool


First off just measure and trace out how big you want your holes. I recommend leaving the middle as support but its pretty strong either way.
The inside is hollow by the way. Then measure and trace one big rectangle
on the backside to about the same size as your air box inlet thats it.



Just cut two holes in the front And cut one in the back and your Set.


and there you have it the ram air mod.



I did notice some increased hp after this mod.


I also added somes grills as a nice touch.


Well thats it kids.. its very simple once you get started. Enjoy

The only down side to this is in previous tests it has been noted that the only way to get any kind of gains from this are if you seal the hood to the airbox. Like using a stock ram air hood with raised air box & some sort of seal so when the hood is closed it basically seals the openings to the airbox.

The BGRA system used to be the choice of alot of guys to seal the gap but those went outta production a few years ago.

I did this to my car a while back. Can't really speak for the results. SOTP results are not very accurate. Probably doesn't hurt though.

I finished mine with door trim.

^^At least this set-up has the raised airbox & could be sealed. The OP's set-up will just let air into the engine bay. With that filter set-up it just sucks air from the engine bay basically, its impossible to seal it.

And believe me from personal experience when you open the hood & dont seal it to the raised airbox your gonna get a ton more dirt in your engine bay. Mine still isnt sealed, I just popped out the internal hood baffles & my engine bay is constantly dirty.

I dont think thats a raised air box on Spd-Klz's car, it looks like the stock one to me...and I dont know that the will fit under a stock steel hood anyway (it might but I dont know that it will.)

AND for what its worth Hawks use the short airbox so I dont think that makes any difference.

I think he meant the raised design vs. the K&N design. I do have the stock one though - not the WS6 one.

To be honest, I've never considered sealing it...

Gotcha! I didnt even look at the OPs pics enough to notice that.

Yea, I was generalizing kinda, LOL. I was mainly meaning that even though he will get a little more fresh air to the filter with this mod it still doesnt seal the box to the opening & will let alot more dust into the engine bay. This will also cause the air filter to get a little dirtier faster.

This is an old mod idea. I did it years ago and I was far from the first.

I put velcro around the edges of the front openings and cut sheet plastic to make rain blockers. Some water got into the airbox opening driving open in heavy rain.

I used foam sealing tape on the backside to make a seal. It's not real tight, but keeps airflow going straight to the airbox. I do notice that the filter gets dirtier quicker, and my IAT's stay lower than a WS6 car with the stock baffles in. But no detectable gain at the track.

All in all, I think it's an ok mod and would probably do it again.

Regardless if it's sealed or not, the key is that it's letting cold, fresh air into the engine bay right where the filter will pick it up.
