Speed Density Kit

The Total Racing Products Speed Density Kit – Standard Version – R35 GTR offers a superior tuning solution for your vehicle. By utilizing MAP data instead of MAF data, this kit provides enhanced accuracy and reliability, making it ideal for performance enthusiasts. A key benefit of switching to Speed Density tuning is the ability to install vent-to-atmosphere (VTA) blow off valves without encountering fuel mixture issues. Furthermore, a Speed Density tune is known to be better mannered for street driving and effectively removes the common obstacle of maxing out the stock MAF sensors. The TRP’s SD Harness is designed as a simple plug-and-play solution, seamlessly substituting the intake air temperature reading from the intake pipe to the upper intercooler pipe to ensure accurate temperature readings. Installation is straightforward: simply plug the conversion harness into the OEM connectors on your passenger side engine harness. Then, remove the factory sensor on your intercooler pipe and replace it with the new sensor provided with the kit. The wiring in this harness is constructed with TXL wire, featuring XLPE insulation that is resistant to heat, flame, gasoline, grease, and acid. This robust construction ensures reliability in extreme temperature applications, ranging from -40°F to 257°F.
