2017-2021 Honda Civic Si "Cobra" Cold Air Intake System by PRL Motorsports

There's a reason our Cobra Cold Air Intake Systems is a constant topic of discussion and so highly regarded. 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. The Cobra CAI utilizes a 4" volume from the air filter into the MAF Housing 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

  • 15 horsepower and 12 ft/lb torque gains in comparison to stock with Street MAF housing WITHOUT TUNE - Read More Here!
  • 20 horsepower and 15 ft/lb torque gains in comparison to stock with Race MAF housing WITH Race MAF basemap calibration on Hondata and/or KTuner – Read More Here!
  • Larger gains to be seen at higher power levels with custom tuning

Please Note

  • The PRL USDM Windshield Washer Reservoir Conversion Kit (PRL-INT-10G-CAN) is required for CDM vehicles.
  • 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

PRL Cobra CAI

Installation on the intake was a little difficult, but the sounds it makes was well worth it. Highly recommend this intake.
I would purchase it all over again.

A Must Need!

If you have an SI, then you need this. This made my car sound amazing and with a tune, my car drives way better than stock. Definitely worth it. Don't wait.
