Heyya, I was wondering if anybody know if this is true about Spec-D® - Aluminum Chrome Cold Air Intake System.. They claim it will give our celi's a 15 - 20 hp boost from just installing there air intake. I don't think that is possible, but just wanna know. I couldn't find any thread about it & check other celi's fourms as well.
Any possible info would help, thanks..
