i bought my 02 z28 used. as far as im aware, there's nothing done to it at all. I've been looking through other peoples' pictures of their ls1 f-bodies, and on their engine pictures, their stock air box is black, with some words on it or something.
my airbox has the gm performance parts logo on it. i was wondering if that has any significance to performance at all, or if it was the previous owner just putting some dumb sticker on their car.
thanks for your input

 

IF you have the air baffles you still have the stock lid.

That sticker could give some performace benefits depending on color though.

 

stickers add horsepower.

 

i dont have an ls1 but my k&n sticker added 10 hp...amazing

 

Here is a pic of an SLP (all aftermarket look basically the same) and stock one, which does yours look like:
