Constructed of 3.0-inch diameter carbon fiber tubing with K&N cone filter elements and 3-ply silicone couplers, the Big SF Intake System opens the door to huge power gains, but is equally at home on a stock GT-R using COBB's Big SF Off-The-Shelf maps.
In stock form, the R35 ECU measures airflow using a Mass Airflow (MAF) sensor located in the stock intake system. As modifications add up and increase power, the airflow can increase to the point that it exceeds the MAF sensor"s maximum capacity, preventing the ECU from accurately measuring air mass, and thus unable to deliver the appropriate amount of fuel. The Big SF Intake increases the inner diameter of the intake tubing, increasing the cross section of the intake and allowing the MAF sensor to read lower for the same amount of ingested air. This gives the sensor the necessary headroom to read accurately for airflow higher than the stock system was designed for.
Installation requires no cutting or trimming or removal of the bumper skin or bumper support and can be completed with simple hand tools. Simply remove the stock airbox and bolt the Carbon Fiber Big SF intake into place in just minutes!
