This intake offers an astonishing 50.6% increase in airflow over the stock intake, and maintains a 99.81% efficiency rating at 653 CFM when running a cleanable filter. The dry filter showed a 49.6% increase in airflow while remaining 99.68% efficient at 653 CFM. * ISO 5011 Filtration Testing. A mountain of dust and our 1/2 million dollar lab is how far we've gone to make sure your engine is protected. * Airflow with options. When its cool out, remove the included plug from the secondary box opening, and engulf an insane amount of air. With the secondary port open, the restriction of the air flow is decreased. Lower restriction equals better airflow. * Cleanable or dry filters. You pick. We offer intakes with two types of filters: Cotton (cleanable) or Dry (disposable). Since you are not sacrificing performance with either choice, the decision comes down to would you rather throw away the filter or clean it. The part numbers for intakes with a dry filter end with 'D'. * Fits better than stock. Easy to install with a fitment that rivals the OE intake. Securely mounts to the frame with only one (1) attachement point. * Get the scoop. Ram more cool air to your engine with an optional scoop. Mounts securely just under the bumper. We test all of our scoops to the SAE J2554 Water Spray Removal Test Standard to ensure your engine is protected from rain and splashing. Please be aware that the scoop will only work on stock bumpers. Do not submerge. * Know when to clean your filter. Just pop your hood and know when its time to service your filter thanks to our signature clear lid. Custom molded for strength and to accommodate for a huge filter. The lid shields the filter from engine heat and debris for better performance and longer filter life. * Quality Down to the Last Screw. High quality products are an obsession of ours, so you only get the best components when buying S&B
