Cobb Tuning Big SF Intake System - GT-R 08-14
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 Stage1 and Stage2 vehicles. Big SF Intake maps are
available for download from the Nissan GT-R Accessport Map Database.
