- No Calibration Required For Standard Bore MAF Housing
- Big Bore MAF-Specific Calibration is Required For Big Bore MAF Housing
- Big Bore MAF Basemap Calibrations Available in Both Hondata and KTUNER
- Two Step Performance TSP and Phearable Calibrations Compatible By Selecting Race MAF Option
If we could recommend an intake system for the 1.5L Turbo Civic Platform it would our Cobra Cold Air Intake System . However, for customers that do not wish to run a CAI, our Short Ram Intake System is also an option.
Our CNC machined billet aluminum MAF Housing was designed to provide factory-spec fuel trims -4 Percent of factory STFT and LTFT for optimal drivability and performance. This SRI utilizes a 4 Inch air filter and is available with two different MAF housing choices; a Standard Bore housing and a Big Bore housing. Both housings utilizes the factory MAF sensor, but feature two different diameters and profiles.
As mentioned above, the Standard Bore housing is designed to provide factory-spec fuel trims WITHOUT any tuning whatsoever. The Big Bore housing allows a 50 Percent larger volume of air in comparison to the Standard Bore housing, which is why a tune IS required. This larger volume of airflow reduces pumping loss and creates an unrestricted air path to feed the MAF housing with ambient temperature air.
Customers can switch between MAF housings without having to buy another intake system by purchasing our MAF Housing Conversion Kit
Customers can convert to a Cold Air Intake with our Cold Air Intake Conversion Kit
Performance Gains:
- 15 horsepower and 12 ft/lb torque gains in comparison to stock with Standard Bore MAF housing Without Tune
- 20 horsepower and 15 ft/lb torque gains in comparison to stock with Big Bore MAF housing WITH Big Bore MAF basemap calibration on Hondata and/or KTuner
- Larger gains to be seen at higher power levels with custom tuning
Please note that short ram intakes are extremely sensitive to heat-soak with this chassis which is why we recommend our CAI. Performance gains will lessen as the engine and intake begins to heat-soak.
