From our testing, we have found that the factory air intake assembly for the 2011 GT (with the new "5.0" 4-valve engine) flows 748.7 CFM, which is a REDUCTION in airflow of approximately 50 CFM versus the factory 2010 GT air intake assembly, which flowed right at 800 CFM. This difference is due to the fact that the new vehicle now features a single round throttle body that is placed lower in the engine compartment. The new inlet tube is both smaller and has a different airflow path, which makes it more restrictive than the one that was used on the 2010 GT models.




YES, the C&L Air Intake System for the 2011 GT
works very well with the Boss Intake manifold and the Boss Track Key Tune.

The V6 model now features a much more powerful 3.7L engine, which produces just over 300 HP -comparable in peak HP to the "old" V8 engine used in the 2005-2010 model GT vehicles. The factory air intake assembly for this vehicle retains the same "cold/fresh air" feature as the GT, but due to the fact that it has a throttle body that is ½" smaller in diameter than the new GT (along with a different air inlet tube and air box assembly), its flow capacity comes in at 685 CFM. For comparison purposes, the factory 2005-2009 GT air intake assembly flowed 550 CFM.

By looking at the flow data, you will see that our NEW 2011 GT Air Intake System in tune required configuration flows 47% more than the factory air intake assembly used on the 2011 GT.

In No-Tune configuration, our 2011 Mustang GT Air Intake System flows an outstanding 45% more than the factory air intake assembly.

We have been working closely with several different companies who are testing various performance upgrades for the 2011 Mustang for upcoming magazine features in popular Mustang publications. From their testing, our intake has shown to increase horsepower by roughly 11 to 12 HP as a direct bolt-on BY ITSELF in a "no tune" configuration while still using the factory stock computer programming. In a "tune required" configuration, where the no-tune insert is removed and adjustments to the mass airflow table is the ONLY change made in the tune, an additional gain of approximately 3 more horsepower has been realized. This means that a MAXIMUM of 14 to 15 HP can be attributed to the air intake assembly alone. With custom computer tuning, gains of as much as 28 to 30 HP over stock in the upper RPM range is a realistic improvement when using 93 octane fuel. Peak gains that are higher than this are possible in the "midrange" (around 5,400 RPM), which is where the factory timing level dips down by roughly 3 to 4 degrees as compared with the rest of the RPM range. This can be seen through close examination of the dyno charts on this page. Bringing the timing up in this area provides a substantially greater increase in performance, as compared to other areas under the horsepower curve.

We STRONGLY caution you regarding the performance claims of other companies selling competing air intake products. Be aware that we are the ONLY company that is providing not only actual flow test data regarding our various system configurations, but ACTUAL mass airflow calibration information which shows the accuracy of our "no tune" configuration. This is because we have proprietary test equipment that is utilized throughout our product development which helps to ensure that we make the best possible system. Our dyno test data clearly shows the actual air/fuel ratio, ignition timing level and engine coolant temperatures. This proves that the gains shown are TRULY attributed to our air intake upgrade and not some other factor which could effect the results. The testing shown on this page was performed by Arthur Wang at Trackmasters (www.etrackmasters.com) on a totally stock 2011 GT using our "no tune" required upgrade. Due to exclusives with magazine publishers, we will provide the results of the testing from other shops that utilized custom tuning in conjunction with our system just as soon as we are allowed. We have posted numerous "back-to-back" pulls in each configuration, and have presented the "average" pull of each set of tests (with the SAME conditions) to show the ACTUAL gains. We could have very easily taken the "lowest" base test and the "highest" after test and mis-represented that our "no tune required" system for the new GT makes 15 to 16 HP. Although we have tests that clearly SHOW those gains, they are not valid.

In this vehicle application, the throttle body diameter dictates that the air intake assembly must reduce down to 3.5" REGARDLESS of the size of the air filter or mass airflow section. Only so much airflow can be passed through an opening of this size. No air intake design can "work around" this and somehow provide greater gains than what is possible given the size of the throttle body. Pay CLOSE attention to the claims of others and look at what they are selling. Don't be surprised when a "new" competing air intake assembly shows up with features that were clearly "inspired by" our system. Our knowledge and experience comes from making air intake upgrades for over 18 years. We trust that any savvy enthusiast will see attempts at emulating our products for what they are. Please keep this in mind, should you decide to compare our product and test results with the claims of competitors.

Initial dyno testing of our No-Tune Air Intake System for the 2011 Mustang GT is provided below. This dyno graph at right represents the average runs for both the stock configuration and the C&L No-Tune configuration. To guarantee that gains can only be attributed to the installation of the air intake system and no other factor, care was taken to insure that timing, air fuel ratio, and operating temperature levels were the same for every run.

We will update this page with independent dyno test comparisons just as soon as the information is available. Keep checking this page for future updates…
