The Attack Blue filter works extremely well when a supercharger's involved! It allows a great deal of air to feed your LS9 & create power without sacrificing filtration! Receive huge rear wheel gains just by replacing the stock filter with the Attack Blue! No tune needed! Its Patent Pending low restrictive open mouth and narrow back design allows more free flowing air to rush through this filter over any O.E replacement filter on the market! No surging! Does not void your factory warranty! 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. A new one needs to be purchased. Attack Blue's cotton media keeps your filter breathing deep longer. Since its washable & reusable it could very well be the last filter you buy for your Corvette! Don't be surprised if you see you're getting better gas mileage too!
Filter comes pre-treated, ready to use. Use Attack Blue special formulated Cleaning kit which DOES NOT CLOG OR FOUL THE SENSORS! (Not included, see below)
