Understanding the 2016 ford mustang ecoboost premium: Features and Specs
The 2016 model year was a pivotal one for the Mustang, as it refined the sixth-generation (S550) platform. The Premium trim level specifically elevates the experience by adding interior comforts that make it a much better daily driver than the base model.
At the heart of the car is the 2.3L EcoBoost four-cylinder engine, producing 310 horsepower and 320 lb-ft of torque. This engine uses a twin-scroll turbocharger to reduce lag, providing a power curve that feels surprisingly meaty in the mid-range.
The “Premium” designation isn’t just a badge; it includes the Sync 3 infotainment system, which was a massive upgrade over the previous MyFord Touch. You also get leather-trimmed heated and cooled seats, selectable drive modes, and a better nine-speaker audio system.
The Benefits of the S550 Platform
One of the biggest advantages of this generation is the Independent Rear Suspension (IRS). Unlike older Mustangs with a solid rear axle, this car handles bumps and corners with much more composure and grip.
This setup makes the car an excellent candidate for autocross or spirited canyon driving. The weight distribution is also slightly better than the GT model, as the four-cylinder engine is lighter and sits further back in the engine bay.
For the DIY mechanic, the engine bay is relatively spacious compared to modern European turbo cars. Most components like the battery, air box, and oil filter are easy to access with standard hand tools.
Common Mechanical Issues: What Every Owner Should Watch For
While the 2.3L engine is generally reliable, it has a few “Achilles’ heels” that can cause major headaches if ignored. Being proactive with these specific parts can save you thousands of dollars in engine repairs.
The most discussed issue in the community is Low-Speed Pre-Ignition (LSPI), often referred to as “Ecoboom.” This occurs when the engine is under high load at low RPMs, causing a premature explosion in the cylinder that can break a piston rod.
To avoid this, never “lug” the engine. If you need to accelerate quickly while in a high gear, always downshift to get the RPMs up before applying heavy throttle. This simple habit is the best way to protect your internal components.
The Low-Pressure Fuel Sensor Issue
A very common failure point on the 2016 ford mustang ecoboost premium is the low-pressure fuel sensor. When this part fails, it can cause the car to stumble, lose power, or even trigger a lean condition that damages the engine.
Ford eventually released an updated “BU” version of this sensor that is much more robust. If your car still has the original sensor with a “flat” top, you should replace it immediately with the newer, “finned” version as a preventative measure.
Replacing this sensor is a 10-minute job for a DIYer. You only need a basic socket set and some rags to catch a small amount of fuel spray when you disconnect the old unit.
Evap Purge Valve Failure
Does your Mustang struggle to start or idle roughly right after you fill up the gas tank? This is a classic symptom of a failing Evap Purge Valve. This valve gets stuck open, allowing fuel vapors to flood the engine.
This part is located right on top of the engine and is very inexpensive to replace. Ignoring it can eventually lead to catalytic converter damage due to the rich fuel mixture, so fix it as soon as you notice the symptoms.
Simply disconnect the electrical harness and the two plastic clips holding the vacuum lines. Swap in the new valve, and your idle issues should disappear instantly.
Essential Maintenance Schedule for Longevity
Turbocharged engines are much harder on their oil and cooling systems than naturally aspirated engines. Following the factory “Normal” maintenance schedule is often not enough if you drive the car enthusiastically.
You should aim for oil changes every 5,000 miles rather than the 7,500 or 10,000 miles some monitors suggest. Always use a high-quality Full Synthetic 5W-30 oil that meets Ford’s WSS-M2C946-B1 specification.
The turbocharger is cooled and lubricated by the engine oil. Using cheap oil or extending drain intervals can lead to carbon deposits inside the turbo, eventually causing it to fail or lose efficiency.
Managing Carbon Buildup
Because the 2.3L EcoBoost is a Direct Injection (DI) engine, fuel never washes over the intake valves. Over time, oil vapors from the PCV system bake onto the hot valves, creating carbon buildup.
This buildup restricts airflow, leading to lost horsepower and poor fuel economy. Every 50,000 to 60,000 miles, consider having a “walnut blasting” service performed to manually clean the valves.
Installing a high-quality catch can is a great DIY project that can slow this process down. It traps the oil gunk before it ever reaches your intake manifold, keeping your engine cleaner for longer.
Spark Plug Maintenance
Spark plugs in a turbo engine live a hard life. The high cylinder pressures can wear out the electrodes quickly, leading to misfires under boost.
Check your spark plug gaps every 20,000 miles. Most experts recommend gapping them to 0.028 inches, especially if you plan on running a performance tune. Use Iridium plugs for the best balance of longevity and conductivity.
When replacing plugs, always do it on a cold engine to avoid damaging the threads in the aluminum cylinder head. A small amount of anti-seize on the threads is a good idea for future removal.
Top Performance Modifications for the S550 Platform
The 2016 ford mustang ecoboost premium responds incredibly well to modifications. Because it is turbocharged, you can find significant power gains without ever opening up the engine block.
The first and most important modification is an upgraded intercooler. The factory intercooler is notoriously small and suffers from “heat soak” after just one or two hard pulls, causing the ECU to pull timing and reduce power.
A larger front-mount intercooler (FMIC) keeps the air entering your engine cool and dense. This doesn’t just add power; it makes the power consistent even on hot summer days.
Tuning and Software Upgrades
Once you have a better intercooler, an aftermarket tune can transform the car. Companies like Cobb, Ford Performance, and Unleashed offer tunes that can add 30-60 horsepower and nearly 70 lb-ft of torque.
A tune optimizes the boost pressure, air-fuel ratios, and timing. However, keep in mind that tuning your car can potentially void your powertrain warranty, so proceed with caution if you still have coverage.
If you want to keep your warranty intact, the Ford Performance Calibration is a great middle ground. It is 50-state emissions legal and provides a significant bump in low-end torque while maintaining factory-like reliability.
Suspension and Braking
Power is nothing without control. If your car didn’t come with the Performance Pack, upgrading your brake pads and fluid is a must for any spirited driving. DOT 4 brake fluid has a higher boiling point, which prevents a “mushy” pedal during hard use.
Lowering springs and thicker sway bars can further sharpen the handling. These mods reduce body roll and make the car feel much more planted when diving into corners.
For the best “bang for your buck,” look into a set of vertical links for the rear suspension. These replace the flimsy factory pieces and significantly reduce “wheel hop” during hard acceleration from a stop.
Interior and Tech: Maximizing the Premium Experience
The cabin of the Premium trim is where you spend all your time, so it makes sense to keep it in top shape. The leather seats require regular conditioning to prevent cracking, especially in the side bolsters where you slide in and out.
Since the 2016 model features Sync 3, you have access to a much faster interface than older models. If your system feels sluggish, check for software updates on the Ford owner portal that can be installed via a USB drive.
For those who want modern smartphone integration, 2016 was the first year that could support Apple CarPlay and Android Auto. However, you may need to swap out the USB hub in the center console for a newer version to enable CarPlay.
Improving the Sound Experience
While the nine-speaker system is decent, many owners find the “Active Noise Control” (ANC) annoying. This system pumps artificial engine noises through the speakers to make the four-cylinder sound more like a V8.
If you prefer the natural sound of your turbo and exhaust, you can disable the ANC using a software tool called FORScan or by disconnecting the microphones in the headliner.
Adding a small powered subwoofer to the trunk can also fill out the sound stage without taking up too much room. The factory speakers are clear, but they lack the deep punch that many enthusiasts crave.
Frequently Asked Questions About the 2016 ford mustang ecoboost premium
Is the 2016 Ford Mustang EcoBoost Premium a reliable daily driver?
Yes, it is very reliable if you follow a strict maintenance schedule. The key is using high-quality synthetic oil, changing your spark plugs often, and avoiding “lugging” the engine at low RPMs.
Can I run 87 octane fuel in my EcoBoost Mustang?
While the car can run on 87 octane, the ECU will significantly reduce power to prevent engine knock. To get the advertised 310 horsepower and protect the engine, 91 or 93 octane premium fuel is highly recommended.
What is the most common cause of a Check Engine Light on this car?
The most frequent culprits are the Evap Purge Valve and the Low-Pressure Fuel Sensor. Both are relatively cheap and easy to replace yourself with basic tools.
How can I tell if my car has the Performance Pack?
Look for large four-piston Brembo front brakes, a gauge cluster between the center vents (Oil Pressure and Boost), and 19-inch black wheels. These are the tell-tale signs of the factory Performance Package.
Does the 2016 model have Apple CarPlay?
It supports it, but you may need to update the Sync 3 software to version 2.0 or higher and replace the physical USB hub in the dashboard with a CarPlay-compatible part number.
