More power with as little noise as possible. That was the idea. But really, noise is not that big of a deal. Seeing someone complaining about the noise with Volant on another thread got me curious.
Is the stock intake very restrictive?
The 18hp gain claimed by AFE. That is with or without tune? Is that real at all? If true without a tune that could mean a restrictive intake.
I think the concesus on aftermaket intakes is very little to nothing at all in the way of power gains without an associated tune. Usually a noticable increase in engine sounds upon pressure to the "go" pedel. Looks cool in the engine bay.
