| Pipercross Viper or HKS Super Power Flow
Hi all. I currently have a Pipercross Viper induction kit and today I reconnected the cold air feed after a while of leaving it off. I've heard about the HKS Super Power Flow kit and am deciding whether to sell the Pipercross on and buy the HKS or just make do with the Pipercross.
Does anyone have experience with the HKS or know any performance figures with either kit? |
