The aFe POWER AFE77-46104 SCORCHER GT Module unlocks meaningful power gains in the 2017-2019 Nissan Sentra Nismo and SR Turbo by altering MAP and IAT sensor signals to increase turbo boost pressure, improving throttle response and overall output. Verified on aFe's in-house dyno at up to +14 horsepower and +29 lb-ft torque, the AFE77-46104 installs in approximately 30 minutes using the OEM factory-style connectors already in the vehicle harness. No cutting, splicing, or ECU modification is required. An in-cabin LED switch provides on-the-fly power setting adjustment across four modes, and the module leaves no trace on the ECU when removed. This module is NOT legal for sale or use in California or states adopting CARB emission standards.

aFe POWER is a California-based performance parts manufacturer producing air intakes, exhaust systems, power modules, and drivetrain components for the aftermarket. The SCORCHER GT module line is aFe's entry-level in-line boost enhancement platform, designed for turbocharged vehicles where meaningful power gains can be achieved through intelligent sensor signal management without ECU remapping. Every AFE77-46104 unit is 100% tested before leaving the factory.
The AFE77-46104 SCORCHER GT module intercepts the MAP (Manifold Absolute Pressure) and IAT (Intake Air Temperature) sensor signals between the sensors and the ECU. By modifying these signals, the module causes the ECU to increase turbo boost pressure, resulting in higher output. aFe's in-house dyno testing shows gains of up to +14 horsepower and +29 lb-ft of torque on the 2017-2019 Sentra Nismo and SR Turbo 1.6L turbo engine.
Will the AFE77-46104 work on the Sentra SR Turbo as well as the Nismo?Yes. The AFE77-46104 is compatible with both the 2017-2019 Nissan Sentra Nismo and the 2017-2019 Sentra SR Turbo, as both trim levels use the same I4-1.6L turbocharged engine. Note that this module will NOT fit the Sentra L4-1.8L naturally aspirated engine. Confirm your Sentra has the 1.6L turbo before ordering.
Does the AFE77-46104 require any tuning after installation?No additional tuning is required. The AFE77-46104 functions as a plug-and-play in-line module that the ECU interprets as modified sensor readings. No aftermarket tune, ECU flash, or dealer service is needed to operate the module. The four power settings (Stock, Sport, Sport+, Race) are accessible via the in-cabin LED button after installation and require no further calibration.
Can I use the AFE77-46104 with other aFe products?Yes. aFe POWER states that the AFE77-46104 is compatible with their performance intake and exhaust products, and the gains are optimized when combined with aFe performance products on the same vehicle. aFe does not recommend using the module in conjunction with any other tuner or third-party performance module simultaneously.
Will removing the AFE77-46104 affect my ECU or warranty?The AFE77-46104 leaves no footprint on the ECU when removed. It operates entirely through the external sensor wiring harness and does not write to or modify the ECU's memory. Removing the module restores the vehicle to its factory sensor signal configuration. For factory warranty concerns, consult your dealership regarding their policy on in-line performance modules, as policies vary by manufacturer and dealer.
What are the four power settings on the AFE77-46104?The four power modes are Stock (Green LED), Sport (Yellow LED), Sport+ (Orange LED), and Race (Red LED). Stock mode returns the vehicle to factory output. Sport, Sport+, and Race progressively increase the boost signal alteration, delivering higher power outputs at each step. The Race setting corresponds to the maximum dyno-tested gains of +14 HP and +29 lb-ft. The mode can be changed at any time while driving using the in-cabin LED switch.
Is the AFE77-46104 legal in California?No. The AFE77-46104 SCORCHER GT module is not CARB exempt and is not legal for sale or use in California, or other states that adopt California Air Resources Board (CARB) emission standards. This module is intended for off-highway or racing use in those states. Buyers in affected states should confirm local regulations before purchasing.
How long does installation of the AFE77-46104 take?aFe rates the AFE77-46104 installation at approximately 30 minutes for the average DIY installer. The module uses factory-style OEM connectors that plug directly into the existing Sentra Nismo or SR Turbo wiring harness at the sensor locations. No cutting, soldering, or harness modification is required. The in-cabin switch should be mounted in a convenient, accessible location and routed through the firewall or door sill to keep wiring clean.
