Product Description

Fitment Notes:


Please Read Before Ordering:

  • 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

Technical Notes:

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.

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 Short Ram Intake with our Short Ram Intake Conversion Kit

Performance Gains:

  • 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

Do yourself a favor and buy this intake!
Andrew Stout (San Clemente, CA) 2/16/2019 9:49 PM
I could not be any happier! First off, the car sounds amazing and you can really hear the turbo! Anyone that's debating getting a BOV should buy this instead. In addition to getting the desired turbo sounds you're obviously also getting the functionality of the cold air that our cars so desperately yearn for. Well worth the money!

Worth every cent!

This intake is incredible! High quality build with a fairly easy install. The longest part about the install is just removing the plastic clips from under the car. Other than that, it's very simple and takes a short amount of time! I'll continue to buy from PRL in the future!
