2023 Ford Explorer St Performance Upgrades

The Ford Explorer ST has quickly become a favorite among SUV enthusiasts looking for a blend of practicality and performance. For the 2023 model year, owners are eager to explore options to enhance the already impressive capabilities of this vehicle. This article will delve into some of the most popular and effective 2023 Ford Explorer ST performance upgrades, helping you make informed decisions to take your driving experience to the next level.

Engine Performance Upgrades

The heart of the Explorer ST is its 3.0-liter EcoBoost V6 engine, which delivers a potent 400 horsepower and 415 lb-ft of torque right from the factory. However, there's always room for improvement. Several aftermarket upgrades can further boost engine performance:

ECU Tuning

One of the most impactful upgrades is ECU (Engine Control Unit) tuning. A custom tune can optimize the engine's parameters, such as fuel injection, ignition timing, and boost pressure, to unlock hidden power. Reputable tuners can provide customized tunes specifically for the 2023 Explorer ST, taking into account factors like your driving style and desired performance gains. Some benefits of ECU tuning include:

Increased horsepower and torque
Improved throttle response
Enhanced fuel efficiency (in some cases)
Optimized shift points (for automatic transmissions)

Always choose a reputable tuner with proven experience tuning Ford EcoBoost engines to ensure reliability and avoid potential damage.

Cold Air Intake

A cold air intake replaces the factory airbox with a less restrictive system, allowing the engine to draw in a larger volume of cooler air. Cooler air is denser and contains more oxygen, leading to improved combustion and increased power. Cold air intakes often include a larger air filter and smoother intake tubing. Key benefits include:

Improved airflow to the engine
Increased horsepower and torque
Enhanced engine sound

When selecting a cold air intake, ensure it's designed specifically for the 2023 Explorer ST for optimal fitment and performance. Look for systems that utilize a heat shield to further isolate the intake from engine bay heat.

Performance Exhaust System

Upgrading to a performance exhaust system can significantly improve exhaust flow, reducing backpressure and freeing up horsepower. Performance exhaust systems typically feature larger diameter piping, mandrel bends, and high-flow mufflers. Besides the performance gains, a performance exhaust also enhances the sound of the engine, giving it a more aggressive and sporty tone. Consider these factors when choosing an exhaust system:

Cat-back vs. Axle-back: Cat-back systems replace the exhaust from the catalytic converter back, while axle-back systems only replace the muffler and tailpipes. Cat-back systems offer more significant performance gains.
Sound level: Performance exhausts range from mild to aggressive in terms of sound. Choose a system that matches your preferences and local noise regulations.
Material: Stainless steel exhausts offer superior durability and corrosion resistance.

Handling and Suspension Upgrades

While the Explorer ST offers decent handling from the factory, several upgrades can further enhance its cornering ability and overall driving dynamics:

Lowering Springs

Lowering springs replace the factory springs with shorter, stiffer springs, lowering the vehicle's center of gravity. This reduces body roll during cornering, improves handling responsiveness, and gives the Explorer ST a more aggressive stance. Lowering springs typically lower the vehicle by 1-2 inches. Considerations when choosing lowering springs:

Spring rate: Stiffer spring rates provide better handling but can also result in a harsher ride.
Drop height: Choose a drop height that balances aesthetics and practicality.
Compatibility: Ensure the springs are compatible with the factory shocks and struts, or consider upgrading to performance shocks and struts for optimal performance.

Performance Shocks and Struts

Upgrading to performance shocks and struts can significantly improve the Explorer ST's handling and ride quality. Performance shocks and struts offer better damping characteristics than the factory units, allowing them to better control body motions and absorb bumps and imperfections in the road. This results in improved handling, reduced body roll, and a more comfortable ride. Some features to look for include:

Adjustable damping: Adjustable shocks and struts allow you to fine-tune the ride quality to your preferences.
Monotube design: Monotube shocks offer superior performance and durability compared to twin-tube designs.
High-quality materials: Look for shocks and struts made from durable materials like aluminum or steel.

Sway Bars

Sway bars (also known as anti-roll bars) connect the left and right wheels of an axle, reducing body roll during cornering. Upgrading to thicker, stiffer sway bars can significantly improve the Explorer ST's handling responsiveness and cornering grip. Stiffer sway bars transfer more weight to the outside wheels during cornering, keeping the vehicle flatter and improving traction.

Braking Upgrades

While the Explorer ST's factory brakes are adequate for everyday driving, they may not be sufficient for spirited driving or track use. Upgrading to performance brakes can significantly improve stopping power, reduce brake fade, and enhance overall safety.

Performance Brake Pads

Performance brake pads offer a higher coefficient of friction than the factory pads, resulting in improved stopping power and reduced brake fade. Performance brake pads are available in a variety of compounds, ranging from street performance to track-oriented. Choose a pad compound that matches your driving style and intended use. Important Note: Performance brake pads can sometimes be noisier than OEM pads.

Upgraded Brake Rotors

Upgrading to slotted or drilled brake rotors can improve brake cooling and reduce brake fade. Slotted rotors provide channels for heat and debris to escape, while drilled rotors offer additional cooling. However, drilled rotors can be more prone to cracking under extreme heat. Consider these rotor types:

Slotted rotors: Provide good cooling and debris removal.
Drilled rotors: Offer maximum cooling but can be prone to cracking.
Blank rotors: Offer good performance and durability for street use.

Stainless Steel Brake Lines

Stainless steel brake lines replace the factory rubber brake lines with braided stainless steel lines. Stainless steel lines are less prone to expansion under pressure, resulting in a firmer brake pedal feel and improved braking response. This upgrade provides a more confident and precise braking experience.

Wheels and Tires

Upgrading to performance wheels and tires can significantly improve the Explorer ST's handling, traction, and aesthetics. Lighter wheels reduce unsprung weight, improving handling responsiveness, while performance tires offer superior grip. When selecting wheels and tires, consider these factors:

Wheel size and offset: Choose a wheel size and offset that fits the Explorer ST without rubbing or interfering with the suspension.
Wheel weight: Lighter wheels improve handling and acceleration.
Tire size and compound: Choose a tire size and compound that matches your driving style and intended use. Summer performance tires offer superior grip in dry conditions, while all-season tires provide a balance of grip and versatility.

By carefully selecting and installing the right 2023 Ford Explorer ST performance upgrades, you can transform your SUV into an even more capable and exhilarating machine. Always consult with a qualified mechanic or performance specialist to ensure proper installation and compatibility. Remember to prioritize safety and reliability when making any modifications to your vehicle. Enjoy the enhanced performance and driving experience!
