Great price
well worth the money. The auto parts stores near me wanted double the price and they had to special order it. This works great on my k &n setup in my 2008 Ford f-450.

Perfect fit, Nice Price
Building cold air / free flow intake for Yamaha V-Star 950. This beefy, hard to find 5" ID Filter fits like a charm. TONS more surface area than the weenie original intake. Price was very nice.
