Volant's PowerCore Cool Air Intake Kits combine the same horsepower producing features found in their original cool air intakes with the filtering power of their new PowerCore filter. The PowerCore filter is the most revolutionary filter on the market utilizing advanced Ultra Web Nano Fiber technology to offer superior filtration and flow.
I can see an improvement over me old stock intake, but it didn't change the world or anything. It's an easy install and looks pretty good too. I would definitely suggest getting the ram-air duct that comes separately.
