Used for about 4000 miles, perfect condition. The result is an optimized open-airbox design that integrates a fresh air duct inlet to channel cool outside air to the filter. This large open-airbox design allows for a massive 5" inlet conical air filter with integrated velocity stack, free of restrictive shrouding, and channels air through a CFD-optimized 4-ply silicone inlet hose that smoothly increases air velocity to the SuperDuper Turbo Inlet.
