Add Power and Torque with Easy Upgrades

While the 3V 4.6L V8 under the hood of 2005 to 2009 Mustang GT is pretty snazzy from the factory, there's still plenty of room to squeeze out some extra horsepower and torque, and our entry-level Phase 1 Performance Package is a great place to start. This kit improves incoming intake airflow and modifies your Mustang's engine computer with a power tune that gets you excellent amounts of power and torque in an easy, hassle-free package that even costs less than purchasing these parts individually. Our Phase 1 kit comes with an awesome Airaid "Race" Cold Air Intake Kit and an SCT X4 tuner that work together to add over 25 horsepower and 35lb-ft of torque at your Pony's crankshaft that you'll feel the instant you jam your foot into the throttle. Better yet, both components are available here at a lower cost than purchasing each one individually to save you a buck while getting you the performance you need.

High-Quality Airaid "Race" Cold Air Intake

You can always trust our friends and cross-town neighbors at Airaid to put out a high-powered, high-quality intake kit, and their "Race" system is one of the most effective Mustang performance parts that you can grab for your 3V Mustang. This kit combines a high-flow SynthaFlow oiled air filter with a massive and highly-efficient 4.25" roto-molded inlet tube that delivers a huge volume of air to your Mustang's intake manifold for big gains in power after it's been properly tuned. The intake kit is an easy, bolt-on replacement for your Mustang's stock air box and outflows the factory system by a huge margin. Airaid's SynthaFlow air filter even cleans inbound air more effectively to keep dust and grime out of your cylinders while generating more power and torque. The kit includes a complete heat shield mount, hardware, and detailed instructions that makes install simple and hassle-free.

Powerful Tuning from SCT Performance

Adding a bunch of powerful Mustang performance parts to your engine is all well and good, but could be disastrous if your engine's computer isn't ready for them all. That's why we include an SCT X4 handheld tuner with this kit to both add power and to prevent damage to your Pony's modular motor. The X4 comes loaded with several fuel-octane and part-based performance tunes that alter your Mustang's PCM files to squeeze out some extra power and to compensate for altered aspects of your Mustang's performance caused by other components. On top of its tuning, the X4 can also read and clear DTC trouble codes, datalog engine running information, and store up to 10 custom tunes that can be downloaded from your home PC using an included USB cable. The X4 is one of the most versatile tuners on the market and will get you the performance and easy maintenance that you need.

Tuning and your Powertrain Warranty: any aftermarket PCM/ECU tuning can absolutely result in Powertrain repairs not being covered under your manufacturer's warranty, making it effectively voided. Please take a look at Stage 3's Stance on Tuning and Warranties or call us directly at 1-877-578-2433.
