The Ford Explorer ST is a high-performance SUV that blends power, comfort, and capability. One of the simplest and most effective ways to boost its performance is by upgrading the cold air intake (CAI). By improving airflow and increasing the amount of cool, dense air entering the engine, a CAI can enhance horsepower, torque, and throttle response. In this guide, we will explore the top cold air intake options available for the Explorer ST, comparing their features, benefits, and overall performance impact.
Why Upgrade Your Cold Air Intake?
A stock intake system is designed for efficiency and noise reduction rather than maximum airflow. By upgrading to an aftermarket CAI, you can:
- Increase horsepower and torque
- Improve throttle response
- Enhance engine sound
- Achieve better fuel efficiency (in some cases)
Many Explorer ST owners opt for CAI upgrades as part of a larger performance package, including tuning and exhaust modifications.
Top Cold Air Intake Options for the Explorer ST

This intake provides a balance of performance and efficiency, with an oiled cotton filter that captures contaminants while allowing maximum airflow. The roto-molded intake tube optimizes airflow, resulting in improved acceleration and throttle response.
5. Steeda Cold Air Intake
Key Features:
- Direct replacement for factory intake
- Enhances airflow while reducing intake temperatures
- No-tune required for installation
- Available in full intake systems or drop-in filters
Steeda offers cold air intake solutions for those looking for mild or aggressive performance upgrades. Their systems improve airflow efficiency while keeping intake temperatures low, which is crucial for maintaining consistent performance. Steeda also provides drop-in filter upgrades for those looking for an easy and affordable way to improve intake performance without replacing the entire system.
Comparing Performance Gains
While specific horsepower and torque gains depend on factors such as tuning and additional modifications, most aftermarket CAI systems for the Explorer ST provide the following estimated improvements:
- S&B Cold Air Intake: 10-15 HP, 10-12 lb-ft torque
- aFe Momentum GT: 12-18 HP, 12-15 lb-ft torque
- FENFABrication: 8-12 HP, 8-10 lb-ft torque
- K&N Cold Air Intake: 7-10 HP, 7-9 lb-ft torque
- Steeda Cold Air Intake: 5-8 HP, 5-7 lb-ft torque
Tuning your Explorer ST after installing a cold air intake can further increase performance, optimizing air/fuel ratios and boosting power output.
Installation and Maintenance
Most cold air intakes for the Explorer ST are designed for simple bolt-on installation, requiring basic hand tools and minimal mechanical experience. Here are some general installation steps:
- Remove the factory intake system.
- Install the new intake components, following the manufacturer’s instructions.
- Secure all clamps and connections to prevent air leaks.
- Reconnect the MAF sensor (if applicable).
- Test for proper fitment and function.
Maintaining your CAI is essential to ensure optimal performance. Depending on the type of filter you choose:
- Oiled cotton filters need to be cleaned and re-oiled every 10,000-15,000 miles.
- Dry filters require replacement or cleaning every 15,000-20,000 miles.
Final Thoughts
Upgrading the cold air intake on your Ford Explorer ST is a cost-effective way to enhance performance, improve throttle response, and add a more aggressive engine sound. Whether you’re looking for a high-flow system like the aFe Momentum GT or a reliable and durable option like the S&B intake, there’s a perfect CAI for every Explorer ST owner.
By carefully selecting and maintaining the right intake system, you can unlock hidden power and efficiency in your Explorer ST, making every drive more exhilarating. If you’re considering additional upgrades, pairing your CAI with an ECU tune and upgraded exhaust system can take performance to the next level.
