ok ok so I have a question!?....I removed the air box on my 92 SC and I also removed the box from under the airbox and I added a cone filter..what kind of hp do you think that added?...3-5? and what kind of gas milage would you all think it would add?..and what else can I add to make more hp? but also a few MPG?....any help would be great and is it true you need headers and exhaust before adding any sort of pulley?
