When Magnuson Supercharger was looking for a filter for more power, they chose Attack Blue for their system. When stock filters clog, it results in a loss of power. Attack Blue's woven cotton media & deep pleats create a larger filtration surface which allows a greater volume of air to move freely to your engine while maintaining Superior filtration! Traps particles as small as 5 microns!
The Attack Blue is washable and reusable. It’s like dropping in a new filter every time you clean it! Reinforced design prevents warping & leaking. It might be the last air filter you purchase for your Corvette. This filter comes pre-treated!

This filter also comes with a GM O.E filter retainer (Part #1001-500) because the stock filter retainer is glued to the stock filter.
