Steeda Autosports, the world's largest aftermarket manufacturer of Ford performance equipment is once again leading the performance market with our High Velocity Cold Air Intake for Vortech Supercharged 2011-2014 Mustangs. This high performance CAI effectively opens up the intake system even further to allow your five-liter power plant breath much more freely.Our engineers started with a large surface area high-flow nano-fiber air filter, added our famous race-tested velocity stack entry and then designed a black powder-coated heat shield with a durable rubber gasket to seal the shield against the vehicle's hood. Next we increased the MAF housing size to 101mm. To ensure the densest air charge possible we retained the factory cold air feed ducting from the front bumper. Steeda was the first company to do this starting in 2010 with our 2010 GT intake and have carried this innovation over to the 2011 model. We also sealed the black powder-coated heat shield to the hood to prevent any hot air from being sucked in from around the engine compartment. Some manufacturers have chosen to ignore the factory cold air ducting, while others don't bother to seal and isolate the airbox, which are both keys to keeping the lowest air charge temperatures possible. Also, our billet aluminum velocity stack and high flow air filter ensure a clean, streamlined air charge into the engine. This Cold Air Intake is so effective at improving airflow into your blown five-liter engine that a performance re-tune is not just recommended, it is required for maximum performance! In an effort to maximize performance and provide our customers with only the very best products we have partnered with the leader in automotive tuning - SCT Performance.
