An intake could give you 12 HP. You would need some kind of tuning aide. Like an Apexi SARC II. You would need to also do it at a dyno and you might be able to get about 8-12 hp if you correctly tune it. Bolt ons don't really give you any power, to see the true power you need to tune the car correctly. So, it is possible to get more then 2 hp out of it, and you might even get 12hp, I would prove it but I don't have an intake, but on the other hand I do have the Apexi SAFC II.
