Waste of cash. Save up a fuew more $$$ for a cam gears or stall if you have an auto if you want your car to be faster.
Your maf is good for up to 500 hp or so.

I have one and dont use it and I would feal bad about selling it to someone haha. But they do make other ones that work well but that when you get into a diffrent intake heads and cam where you would see any benifit to a larger maf yours is fine for a mostly stock car.
I have a cam and heads 90mm intake and still have the stock maf I have to get a tune to see if its worth it to change my maf with a larger one.

does a bigger intake work well with a ls6 manifold... Something like a 90mm over the stock one..? and what would be a good price pay for a used one...?

I think your kinda confused the LS6 is an intake manifold which you have on your 2002.
YOu can send your LS6 intake off to tpis and get it modified to make it a 90mm for 400 bucks but then you have to get a Throttle body to match it for around 500. But if you plan on using nitrous then get somthing diffrent (STRONGER).
But I did some reserch on it an found that tpis was my best choice for the money. For example a fast 90 intake would be around 800 or so and then another 500 for the TB a savings of 400 bucks or so is the way I looked at it.
