Cobb Tuning 7C1150 Big SF intake system Nissan GT-R R35 VR38DETT

For: Nissan GTR R35 with 3.8 Twin Turbo VR38DETT engines

Works From Stock to Big Power Builds 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. 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!

Increased Induction Sound

Enjoy the increased snarl from your engine and hear the turbo spool more clearly with the addition of the COBB Tuning SF Intake system. Turbocharger induction noise and bypass valve venting sound is much more audible using this intake system.

Easy to Install

The COBB Tuning SF Intake was designed to be easy to install without having to modify your car or remove the bumper skin. 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 SF intake into place in just minutes!

Free Off-The-Shelf Calibrations

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 Off-The-Shelf maps for all supported GT-R vehicles. Big SF Intake maps are available for download from the Nissan GT-R Accessport Map Database.

Why?

Constructed of 3.0-inch diameter aluminum 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 our Big SF Off-The-Shelf maps. Excellent starting point for those that intend significant upgrades down the road.
