Description

2017-2021 Honda Civic Si Short Ram Air Intake by PRL Motorsports

PRL-HC10-INT-SRI-BPRL-HC10-INT-SRI-D

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.

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

PLEASE NOTE

• 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
• Short ram intakes are extremely sensitive to heat-soak with this chassis. Performance gains will lessen as the engine and intake begins to heat-soak.

Applications

• 2017 – 2021 Honda Civic Si

Performance Gains

• +15 horsepower and +12 ft/lb torque gains (Street MAF housing WITHOUT TUNE)
