Free up power and add some beauty to your engine bay with the Dundon Motorsports Carbon Fiber Dual Cone Airbox.  We based this design on the fabled 997 4.0L GT3RS.  It features dual conical air filters from the 4.0RS.  In order for you to keep your stock decklid we created a balance pipe in the bottom area of the airbox to allow air to flow to both filters equally. 

On a stock car this airbox will free up about 5-7whp

On a Dundon Race Header equipped car, this airbox is good for about 8-10 whp!

Note Fan Part 997.624.056.05 is required for fitment on cars with the original fan (most of them have been replaced by 997.624.056.05 by now...)  If you need to source it or are unsure, you can order our option that includes a new fan slim line decklid fan from Porsche
