COBB Tuning is proud to announce the release of our latest addition to our Nissan GT-R performance parts: The COBB Tuning Big SF Intake. The Big SF Intake is a 3-inch ID intake designed to open the door to high-power builds in the future, yet work eortlessly with an otherwise stock GT-R. The Big SF Intake kit future-proofs your intake, so you wonâ€™t need to upgrade this component later if you decide to go down the path of major modications. Furthermore, it installs as easily as our regular SF Intake, without any cutting or trimming of bodywork.
In stock form, the R35 ECU measures airow using a Mass Airow (MAF) sensor located in the stock intake system. As modications add up and increase power, the airow can increase to the point that it exceeds the MAF sensorâ€™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 airow higher than the stock system was designed for. COBB Tuning has used the Big SF Intake to support builds of over 600HP and 600TQ at the wheels, gains of 40% over a stock GT-R!
Changing the calibration of the MAF sensor necessitates tuning changes to recalibrate the ECU. COBB Tuning has you covered here as well with a set of free AccessPORT Big SF Intake O-The-Shelf maps for all supported GT-R Stage1 and Stage2 vehicles. Big SF Intake maps are available for download from the Nissan GT-R AccessPORT Map Database.
The Big SF Intake shares all of the same quality features of its popular smaller brother. Constructed of 3-inch diameter aluminum tubing with TIG welded bracketry and MAF sensor mount and nished with a tough black crinkle coating for an OEM quality appearance. High-ow K&N cone lter elements t through the factory openings in the bumper. Your choice of high-quality COBB Blue or Steath Black silicone couplers are used to join the intake to the factory system.
If you looking to upgrade your GT-Râ€™s intake and are considering modifying your GT-R for more power down the road, the COBB Tuning Big SF Intake will meet your immediate intake-upgrade needs with matching AccessPORT calibrations, and will meet airow demands as you continue to modify your car in your quest for more horsepower. It doesnâ€™t get any better than this!
