Product Details

Part Number: PRL-HC10-INT-SRI-B
Brand: PRL Motorsports
Color: Black

If we could recommend an intake system for the 1.5L Turbo Civic Platform, it would be our Cobra Cold Air Intake System. However, for customers who 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 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 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 Standard Bore MAF housing WITHOUT TUNE
  • 20 horsepower and 15 ft/lb torque gains in comparison to stock with Big Bore MAF housing WITH Big Bore MAF basemap calibration on Hondata and/or KTuner
  • Larger gains to be seen at higher power levels with custom tuning
Fitment:
  • Fits all 2017-2021 Honda Civic Si 1.5T
  • Fits most variant models, including 6MT, CVT, RHD, International Models, Etc.

Graph pictures explanation:
  • 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 begin to heat-soak.
  • Above is a graph of the long term fuel trims with the stock intake w/ air box and factory ECU mapping, or in other words, a bone-stock car.
  • Here is a graph of the long-term fuel trims again, but with our cold air intake (Standard Bore MAF) and factory ECU mapping.
  • This is another long-term fuel trim graph, but with our cold air intake (Standard Bore MAF) and +6psi Hondata off-the-shelf map.
  • Notice how consistent and similar all of the LTFT graphs are. Each graph is within -4 LTFT.
  • Above is a graph of the short-term fuel trims with stock intake w/ air box and factory ECU mapping (stock car).
  • Here is a short-term fuel trim graph with our cold air intake (Standard Bore MAF) and factory ECU mapping.
  • This is another graph of the short-term fuel trims with our cold air intake (Standard Bore MAF) and +6psi Hondata off-the-shelf map.
  • All of the STFT graphs display identical curves and consistency.
