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 Standard Bore housing and a Big Bore housing. Both housings utilizes 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.

Performance Gains:

• 15 horsepower and 12 ft/lb torque gains in comparison to stock with Standard Bore MAF housing WITHOUT TUNE 
  
• Larger gains to be seen at higher power levels with custom tuning
