I replaced mine just because the stock one was shot. Figured why replace it with a part that can break again? The Forge one will last the lifetime of the car, just needs to be cleaned occasionally and maybe a new spring way down the line.
Supposedly they hold boost better, especially for tuned cars. I have no idea. I mean, logically you would assume so just based on the design differences... but what the hell do I know?
