Perfect Combination of Sound and Performance
The S3M Phase 3 Package is built for 2011-2014 F150 owners who want their 3.7L V6 to feel stronger, sound better, and respond quicker every time they step on the throttle. While the engine already delivers solid reliability and respectable power, the factory intake, exhaust, and tuning leave plenty of room for improvement. This package tackles those restrictions from multiple angles by improving airflow into the engine, helping exhaust gases exit more efficiently, and optimizing the truck’s engine calibration. The result is a more responsive truck that feels noticeably more eager when accelerating. Whether you are pulling onto the highway, hauling gear, or simply enjoying the drive, this package gives the truck a more energetic personality without sacrificing everyday drivability.
More Efficient Intake that's Easy to Install
The airflow improvements begin with the aFe Magnum FORCE Stage 2 cold air intake, a system designed to replace the restrictive factory air box and inlet tubing with a much more efficient setup. At the center of the intake is the Pro 5R reusable oiled air filter, which uses multiple layers of cotton media to capture contaminants while still allowing a strong volume of air to reach the engine. The filter sits inside a sealed heat shield assembly that helps protect it from engine bay heat. This allows the engine to draw in cooler, denser air during normal driving conditions. The intake also uses a smooth inlet tube that maintains steady airflow as it routes air toward the throttle body. Together, these improvements help the 3.7L engine breathe easier, which leads to better throttle response and noticeable gains in horsepower and torque.
Aggressive 3" Magnaflow Cat-Back Kit for Sound and Power
Helping the engine breathe on the other side is the Magnaflow cat-back exhaust system included in this package. Magnaflow designed this system with mandrel-bent 3-inch tubing that allows exhaust gases to flow more smoothly than the restrictive factory system. This improved exhaust flow helps the engine operate more efficiently and contributes to increased horsepower and torque. At the same time, the Magnaflow performance muffler gives the truck a deeper and more aggressive tone that adds personality without becoming overwhelming during daily driving. The system retains the factory resonator, which helps keep interior noise comfortable while still delivering a satisfying exhaust note when you accelerate. Built from durable stainless steel and finished with a polished 4-inch exhaust tip, the system also adds a clean, performance inspired look to the rear of the truck.
SCT Livewire TS+ Tuner for Added Power and Insight
Bringing all of these upgrades together is the SCT Livewire TS+ performance tuner. This advanced device connects directly to your truck’s OBD-II port and allows you to upload performance calibrations that adjust fuel delivery, ignition timing, and other important engine parameters. These adjustments help the engine make better use of the improved airflow from the intake and exhaust, unlocking additional horsepower and torque while also sharpening throttle response. The Livewire TS+ features a large color touchscreen that makes navigating menus and monitoring engine data simple. It can display real time gauges, read and clear diagnostic trouble codes, and log performance data to help track how the truck is running. Once the tune is installed, the device can remain mounted on the dash as a convenient performance monitor, giving you both added power and valuable insight into your truck’s performance.

Select Tunes by Octane and Performance
5-Star's tunes turn up your 2011 to 2014 F150 3.7L's power by adjusting its fuel curves, ignition timing, fan control, and a ton of other variables so that your truck makes huge amounts of horsepower and torque. 5-Star's custom tuning even takes into account tire size, drivetrain, and axle ratio so that your F150 operates perfectly with your choice of tune. 5-Star's custom tunes are available in several variations for 87, 89, 91, or 93 octane gasoline to give you a wide range of tuning options.
With its factory tune, 5-Star's test truck put down peak numbers of 220 horsepower and and 218lb-ft of torque. With 5-Star's 93 octane Performance/Tow tune, their truck managed to throw down 233 horsepower and 229lb-ft of torque, a gain of 13 horsepower and 11lb-ft of torque. While the peak gains aren't overly dramatic, 5-Star's 93 octane Performance Tune provided a whopping 210lb-ft of torque at 2500rpm, while the factory tune barely managed to crank out 170lb-ft, and not flattening back out until 2700 rpm. That's a 40lb-ft difference in low-end torque that now comes in earlier than stock, meaning you can still get improved low-end grunt, even if you stick with lower-tier fuel.
