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 Percent of factory STFT and LTFT for optimal drivability and performance.
The Cobra CAI utilizes a 4 Inch 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 Percent 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 Short Ram Intake with ourShort Ram Intake Conversion Kit
Performance Gains:
- 15 horsepower and 12 ft/lb torque gains in comparison to stock with Standard Bore MAF housing Without Tune -Â
- 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 KTunerÂ
- Larger gains to be seen at higher power levels with custom tuning

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. The graph of the long term fuel trims again with, but with our cold air intake Standard Bore MAF Housing and factory ECU mapping.
This is another long term fuel trim graph, but with our cold air intake Standard Bore MAF Housing and +6psi Hondata off-the-shelf map. Notice how consistent and similar all of the LTFT graphs are. Each graph is within -4 LTFT.
