Fitment Notes:
FITS 2017+ HONDA CIVIC SI – FOR NON-SI APPLICATIONS, PLEASE VIEW OUR OTHER LISTING(S)
Please Read Before Ordering:
NO TUNE REQUIRED FOR STREET MAF HOUSING
RACE MAF-SPECIFIC TUNE REQUIRED FOR RACE MAF HOUSING
HONDATA & KTUNER BOTH OFFER RACE MAF BASEMAP CALIBRATIONS
TWO STEP PERFORMANCE "TSP" TUNE ALSO COMPATIBLE BY SELECTING "RACE MAF" OPTION
Technical Notes:
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% of factory STFT & LTFT) for optimal drivability and performance. This SRI utilizes a 4" air filter and is available with two different MAF housing choices; a Street housing and a Race housing. Both housings utilizes the factory MAF sensor, but feature two different diameters and profiles. As mentioned above, the Street housing is designed to provide factory-spec fuel trims WITHOUT any tuning whatsoever. The Race housing allows a 50% larger volume of air in comparison to the Street 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 Street MAF housing WITHOUT TUNE
20 horsepower and 15 ft/lb torque gains in comparison to stock with Race MAF housing WITH Race 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.
