PRL's 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.

• 15 horsepower and 12 ft/lb torque gains in comparison to stock with Street MAF housing WITHOUT TUNE. No Tune Required For Street MAF Housing
  
• 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. Race MAF-Specific Tune Required For Race MAF Housing
  
• Larger gains to be seen at higher power levels with custom tuning
  
• Hondata & KTuner Both Offer Race MAF Basemap Calibrations
