PRL Motorsports Big Bore MAF Housing Short Ram Air Intake System (PRL-HC10-INT-SRI-D)

The PRL-HC10-INT-SRI-D is engineered specifically for the Honda Civic Si 1.5L Turbo models from 2017 to 2021. This Short Ram Intake (SRI) system is a solid alternative for enthusiasts looking to enhance airflow without the complexities of a Cold Air Intake (CAI) setup.

Key Features

• Construction: CNC machined billet aluminum MAF housing ensures precision and durability.
• Air Filter: Utilizes a high-flow 4" air filter designed for optimal airflow.
• MAF Housing Options: Available in Standard Bore and Big Bore configurations, both compatible with the factory MAF sensor.

Performance Specifications

The Standard Bore housing maintains factory-spec fuel trims, achieving -4% of factory Short Term Fuel Trim (STFT) and Long Term Fuel Trim (LTFT) for seamless drivability. In contrast, the Big Bore housing offers a 50% increase in airflow volume, necessitating a tune for optimal performance.

Performance Gains

• Up to 15 horsepower and 12 ft/lb torque with the Standard Bore MAF housing without requiring a tune.
• Up to 20 horsepower and 15 ft/lb torque gains with the Big Bore MAF housing, paired with a Big Bore MAF basemap calibration on Hondata and/or KTuner.
• Potential for larger gains at higher power levels with custom tuning.

Fitment

• Honda Civic Si 1.5L Turbo 2017-2021
• Compatible with various transmission options including 6MT, CVT, and RHD models.

Installation Notes

• Short Ram Intakes can be sensitive to heat-soak; performance may diminish as engine temperatures rise.
• Switch between MAF housings easily with the MAF Housing Conversion Kit.
• Convert to a Cold Air Intake using the Cold Air Intake Conversion Kit for additional airflow benefits.
