I think a smooth intake tube + new filter will make roughly 10 WHP. I'll dyno it next month. The AFE filters are sounding pretty good, but HKS filtration is more than sufficient.

A slightly wider MAF section like what Modshack is doing will net you some gains. I think you will get a few HP from better flowing filters but not sure about smoothing out the intake tubes, I dont think the air gets too turbulent to begin with. But who knows.
