Maximize the performance of your 2017-2021 Honda Civic Si 1.5T with the PRL Motorsports Short Ram Air Intake System. This system is perfectly tailored to fit all model variants including 6MT, CVT, RHD, and International models, providing a substantial boost in power and efficiency without the need to run a full cold air intake setup.

Optimized Design for Enhanced Airflow

Our Short Ram Intake (SRI) System features a CNC machined billet aluminum MAF Housing, designed to deliver factory-spec fuel trims for optimal drivability and performance. The system includes a large 4" air filter and offers two MAF housing options: Standard Bore and Big Bore. The Standard Bore housing requires no tuning, while the Big Bore housing, which allows a 50% larger volume of air than the Standard Bore, requires specific calibration to harness its full potential.

Flexible Configuration and Easy Upgrades

This intake system is designed for versatility:

• MAF Housing Options: Choose the Standard Bore for no-tune convenience or upgrade to the Big Bore for enhanced airflow with required tuning.
• Conversion Kits Available: Easily switch between MAF housing types or convert to a Cobra Cold Air Intake system with our available conversion kits, adapting the setup as your performance needs evolve.

Performance Gains

• With Standard Bore MAF Housing: Gain 15 horsepower and 12 ft/lb torque without any additional tuning.
• With Big Bore MAF Housing: Achieve 20 horsepower and 15 ft/lb torque with the appropriate basemap calibration on Hondata or KTuner. Custom tuning can unlock even greater gains at higher power levels.

Important Considerations

While the Short Ram Intake provides significant performance enhancements, it is more susceptible to heat-soak compared to cold air intake systems. This sensitivity can impact performance gains under prolonged or intense driving conditions, which is why we also recommend our Cobra CAI for those in hotter climates or seeking maximum performance consistency.

Kit Includes:

• Billet Aluminum MAF Housing (Anodized for durability)
• PRL Motorsports High Flow 4" Air Filter
• Options for Standard or Big Bore MAF Housing
• All necessary mounting hardware and comprehensive installation instructions

Enhance your Civic Si's responsiveness, power, and engine sound with the PRL Motorsports Short Ram Air Intake System. It's an ideal solution for enthusiasts looking to improve their vehicle's performance with an easy-to-install, cost-effective upgrade that provides immediate results.
