The unique shape of the DDMWorks RAS (ram air scoop) was designed to accelerate the incoming air from the hood scoop and keep the new intake box under pressure forcing even more cold air into the turbo and engine. Two diverters on the back of the RAS direct the air down into the filter, and the RAS seals with the top of our pressurized filter box (PFB) to ensure a cool ambient air supply.
We also wanted regular maintenance of the car to be unaffected with the intake installed, so even with the RAS mounted to the bonnet of the car, regular maintenance of your engine is just as easy as stock. Access to the spark plugs, oil filter and oil fill are just like stock. The scoop attaches to the bonnet using existing mounting points so there is no drilling or modifications needed for installation.
The RAS can be purchased separately for use with other intake systems that leave an exposed filter in the back of the engine bay. We learned during our thousands of miles of testing that exposed filters without the RAS in place see good temperatures during light cruise, but during long pulls the temperature of the incoming air continued to climb as the turbo heated the air coming in through the scoop. With the simple addition of the RAS on those intakes, temperatures stayed only a few degrees above ambient, which resulted in better throttle response and more consistent power. The RAS is offered in DDMWorks Stainless steel, or for a more stock appearance black matte powder coat.
