I bought this 99 Trans Am a few weeks ago, and I noticed the air-cleaner assembly doesn't look like the pictures of other cars Ive seen, that are supposedly stock. The previous owner said he installed this K&N filter, but the air box seems to be different as well. Also, the inside opening for the hood seems to be different. Instead of ramming air into the front slit of a closed box, like most other pictures, theres this big square opening right above the open box, no lid. I have no idea if the filter is sealing to the hood.

Aftermarket WS6 hood with whatever hood company's air box.

Well, after a few days of researching the internets, apparently I have a Suncoast WS6 Hood and airbox. I'm assuming this is a good thing?

It's not a "bad" thing, but it's not "better" than the OE setup. It's just a different means to the same end -- and a nice option for people who bought a Firebird without the WS6 package

You are correct, that is a Suncoast hood and airbox. I put that setup on my 98. After looking at those last two pics, it looks like the hood is probably not sealing up to the airbox. The hood came from Suncoast with some block foam strips, which I don't see in your pics, to put around the opening under the hood to seal against the airbox. I put this on my hood, but changed to some tall rubber weatherstrip that hooked to the edges of the hood opening. Been a long time, but I think the original foam started to fall off the hood, plus I liked the look of the rubber weather strip more. I also looked up the part number on the filter and, if memory serves, it was used on a mid 90's Vette (just fyi). Lastly, I believe that they supplied a different upper radiator support with the kit too.
