If it's what you want, that's fine. I know a lot of people on in the import scene rave about HKS and would choose it over other products that make more power... that's fine.
But like I said before, I think it's going to be like every short-ram available already. I think we've had enough testing here to prove that the only way to gain power by replacing the stock intake tubes is to go with a CAI... and even then the only real gains are top end where the factory intake drops off.
The factory unit is very efficient and does a good job of sourcing air from outside of the engine bay. It's only downside is that it doesn't make any cool noise.
