Steeda has been building Cold Air Intakes for Ford performance vehicles longer than any other company!
Steeda ProFlow Mustang Cold Air Intake for your S550 opens up the intake system of Ford's 5.0 powerplant and allows it to breathe much more freely than the stock intake system allows, taking your S550 Mustang GT to the next level of performance. Steeda's engineers utilized the OE cold air feed and a large surface area high-flow nano-fiber air filter, added our famous 'racetested' velocity stack entry and then designed an advanced heat shield with a durable rubber gasket to seal the shield against the vehicle's hood. Steeda's precision CNC mass air housing provides the cleanest mass air signal on the market, resulting in smooth off-throttle to on-throttle response. Steeda's S550 CAI utilizes a removable restrictor which allows you to benefit from immediate hp/tq gains, without a tune! If you're looking to squeeze out even more power from Steeda's S550 cold air intake, we offer a tune that allows you to run it without the restrictor.

CAI Fitment

By: on 1 November 2019
The instructions were clear and was easy to follow, important as this is the first time I have worked on one of these vehicles. All went well until fitting the intake to the new air box. It would not clip together properly due to the lip on the air box was distorted into a slight curve. Heating it with a heat gun, I was able to return it to it's proper shape. Once this was done it was easy to fit it in and plumb the hoses. Then came the hard part... removing th sound tube. Using the 10mm combo spanner it took over half an hour and is amost a " break your arm in 3 places job". Once out, plug the hole in the firewall and off we go
