PRL Short Ram Intake Honda Civic Si 1.5T (2016-2021) Street or Race

Fitment Information

• Honda Civic Si 1.5T (2016, 2017, 2018, 2019, 2020, 2021)
• Fits most variant models, including 6MT, CVT, RHD, international models, etc.
  

Important Notes

• No calibration is required for standard bore MAF housing.
  
• Big-bore MAF-specific calibration is required for big-bore MAF housing.
  
• Big bore MAF basemap calibrations are available in both Hondata & Ktuner.
  
• Two-Step Performance (TSP) & Phearable calibrations are compatible by selecting the "Race MAF" option.

Emissions Compliance

This intake does not have a CARB EO Number and does not ship to California.

Specs & Features

• CNC machined billet aluminum MAF Housing
• Utilizes a 4" performance air filter
• Available with two MAF housing choices: a Street housing and a Race housing
• Street housing is designed to provide factory-spec fuel trims (-4% of factory STFT & LTFT) WITHOUT any tuning whatsoever
• Race housing allows a 50% larger volume of air in comparison to the street housing and requires a tune. The increased airflow reduces pumping loss and creates an unrestricted air path to feed the MAF housing with ambient temperature air
  

In the Box

• 1 - PRL Short Ram Air Intake
  

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 base map calibration on Hondata and/or KTuner
• Larger gains to be seen at higher power levels with custom tuning

Technical Notes

If we could recommend an intake system for the 1.5L turbo Civic platform, it would be the PRL Cobra Cold Air Intake System. However, for customers that do not wish to run a CAI, the PRL Short Ram Intake System is also an option. The PRL CNC-machined billet aluminum MAF housing is designed to keep fuel trims at factory specs (-4% of factory STFT & LTFT) for the best drivability and performance. This SRI utilizes a 4" air filter and is available with two different MAF housing choices: a standard bore housing and a big bore housing. Both housings utilize 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% larger volume of air in comparison to the Standard Bore housing, which is why a tune IS required. This larger airflow volume reduces pumping loss and creates an unrestricted air path that delivers ambient temperature air to the MAF housing.

Customers can switch between MAF housings without having to buy another intake system by purchasing the PRL MAF Housing Conversion Kit.

Customers can convert to a Cold Air Intake using the PRL Cold Air Intake Conversion Kit.

However, for customers that do not wish to run a CAI, the PRL Short Ram Intake System is also an option. The PRL 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 utilize 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.
