Why Choose an AFE Cold Air Intake System?

AFE, or Advanced Flow Engineering, has built a solid reputation for designing high-performance intake systems that prioritize both power gains and engine protection. The core principle is simple: by replacing your vehicle's restrictive factory air intake with a system that draws in cooler, denser air, your engine receives more oxygen for combustion. This process results in more efficient fuel burning, which translates to tangible increases in horsepower and torque, improved fuel economy, and a more responsive throttle .

AFE systems are engineered with precision-designed intake tubes and high-flow air filters that significantly reduce airflow restriction compared to stock setups. The company offers various product lines, including the Magnum FORCE, Quantum, and Takeda series, each tailored to different vehicle applications and performance goals. Beyond performance, these systems enhance your engine bay's appearance and produce a more aggressive, throaty sound during acceleration, making every drive more engaging .

AFE Filter Technology: Pro DRY S vs. Pro 5R

The heart of any cold air intake system is its filter, and AFE provides two primary advanced filter options, each with distinct advantages.

Pro DRY S Air Filter

The ​Pro DRY S​ utilizes a state-of-the-art, oil-free synthetic media. Comprising three layers of progressively finer synthetic fabric, this filter is designed for maximum convenience and high filtration efficiency. It boasts an exceptional ​99.2% filtration efficiency, effectively trapping dust and harmful contaminants without the need for messy oils. This makes it ideal for street and light off-road use. The filter is washable and reusable, featuring tall, evenly spaced pleats that provide excellent dust-holding capacity for longer service intervals between cleanings. Its rigid polyurethane construction ensures a no-leak seal over the filter's lifespan .

Pro 5R Air Filter

The ​Pro 5R​ air filter employs a traditional but high-performance design using five layers of progressively finer mesh cotton gauze. This media requires oiling to achieve its maximum filtration and airflow properties. The Pro 5R is also washable and reusable, constructed with 100% polyurethane for durability through multiple cleaning cycles. It typically offers a slightly higher airflow rate, with some applications showing filtration efficiency around 98.6% . This filter is an excellent choice for enthusiasts who prioritize maximum airflow and don't mind the additional step of re-oiling during maintenance.

The following table provides a quick comparison of the two filter technologies:

Performance Benefits and What to Expect

Installing an AFE cold air intake system delivers measurable improvements that enhance your vehicle's overall driving experience.

• ​Increased Horsepower and Torque:​​ By allowing your engine to breathe cooler, denser air, AFE intakes unlock power previously restricted by the factory airbox. Gains vary by vehicle but are often significant. For example, tests on a Ford F-150 Ecoboost showed gains of up to ​19 horsepower and 27 lb.-ft. of torque​ , while a system for a BMW 335i produced up to ​14 horsepower and 18 lb.-ft. of torque​ .
• ​Improved Throttle Response:​​ One of the most immediate notices is a sharper throttle response. The reduced airflow restriction means the engine can react more quickly to driver input, making the vehicle feel livelier and more responsive .
• ​Enhanced Engine Sound:​​ AFE intakes often amplify the engine's natural induction noises, creating a more aggressive, sporty sound under acceleration without being overly intrusive inside the cabin .
• ​Potential for Better Fuel Economy:​​ With more efficient combustion, some drivers experience a slight improvement in miles per gallon, especially during highway driving .

Selecting the Right AFE Intake for Your Vehicle

AFE manufactures application-specific systems for a wide range of trucks, SUVs, and performance cars. The most critical step is choosing a model designed explicitly for your vehicle's year, make, engine, and body style. For instance, the ​aFe Magnum FORCE Stage-2 Pro DRY S​ (part number 54-13057D) is engineered for 2019-2021 GM Silverado/Sierra 1500 models with the 4.3L V6 engine , while the ​aFe Power 54-13061R​ is for the 2021-2024 Ford F-150 with the 3.5L V6 EcoBoost . Always double-check the manufacturer's fitment guide before purchasing.

You must also consider your local emissions regulations. Many AFE intake systems are ​50-state legal​ with an Executive Order (E.O.) number from the California Air Resources Board (CARB), meaning they can be legally used on public roads. However, some are not CARB-exempt and are for "off-road use only," making them illegal for vehicles registered in California . Verify the product's status to ensure compliance.

Professional Installation Guide

While installation procedures vary by vehicle, the general process for installing an AFE cold air intake is straightforward and can often be completed in 45-90 minutes with basic hand tools . Most kits are direct bolt-ons that require no cutting, drilling, or permanent modifications to your vehicle .

General Installation Steps

1. ​Safety First:​​ Park the vehicle on a level surface and ensure the engine is completely cool. Disconnect the negative battery terminal to prevent any electrical shorts .
2. ​Remove Factory Components:​​ Using tools like a screwdriver, wrench, or socket set (common sizes are 7mm, 8mm, 10mm, 11mm, and 13mm), carefully remove the factory airbox, intake tube, and associated components. This involves loosening clamps, unplugging sensor connectors (like the Mass Airflow Sensor), and unclipping wire harnesses .
3. ​Install AFE Components:​​ Follow the instructions to install the new AFE system. This typically involves mounting a new heat shield or housing, connecting the new intake tube, and installing the high-flow air filter. Pay close attention to the orientation of couplings and ensure all sensors are correctly transferred and reconnected .
4. ​Secure and Double-Check:​​ Once everything is in place, tighten all clamps and screws. Reconnect the negative battery terminal. Before starting the engine, double-check that all connections are secure to prevent air leaks, which can trigger check engine lights .
5. ​Initial Inspection:​​ Start the engine and listen for any unusual hissing or whistling sounds that might indicate a leak. Take the vehicle for a short test drive to verify proper operation .

Essential Tips for a Successful Installation

• ​Read the Manual:​​ Always read the entire instruction manual provided with your specific AFE intake before beginning the installation .
• ​Inventory Parts:​​ Lay out all components from the kit and cross-reference them with the manual's parts list to ensure nothing is missing .
• ​Handle Sensors with Care:​​ Be gentle when disconnecting and reconnecting electrical sensors, such as the Mass Airflow (MAF) sensor, as they are delicate and crucial for engine management.
• ​Retain Factory Parts:​​ Keep your original intake components in case you need to revert to stock in the future .

Maintaining Your AFE Cold Air Intake Filter

Proper maintenance is crucial to ensure your intake continues to perform at its best and protect your engine. A clogged filter will restrict airflow, negating the performance benefits.

Cleaning and Re-oiling (Pro 5R Filter)

1. ​Cleaning:​​ Use a dedicated air filter cleaner. Spray the cleaner on the filter, let it soak for the recommended time (usually 10-15 minutes), then rinse from the inside out with low-pressure water to force dirt out of the media. Allow the filter to air dry completely before proceeding.
2. ​Oiling:​​ Once dry, apply a specific air filter oil evenly over the entire outer surface of the filter. The oil will appear red when wet and turn to a sticky, tacky substance once it soaks in. The filter media should be evenly coated but not saturated or dripping.

Cleaning and Drying (Pro DRY S Filter)

1. ​Cleaning:​​ The Pro DRY S filter is cleaned similarly but uses a specialized cleaner designed for synthetic media. It is crucial ​not to use oil​ on a dry filter, as this will clog the pores and severely restrict airflow .
2. ​Drying:​​ After rinsing, the filter must be allowed to air dry thoroughly before reinstallation.

Maintenance Schedule

A general rule is to inspect your filter every 12,000 miles or once a year, and clean it as needed. However, if you frequently drive in dusty or off-road conditions, you should inspect and potentially clean the filter much more often, perhaps every 3,000-5,000 miles .

Troubleshooting Common Issues

Even with a proper installation, you may encounter minor issues. Here’s how to address them:

• ​Check Engine Light:​​ This is often related to the Mass Airflow (MAF) sensor. Ensure the sensor is properly connected and that the filter was not over-oiled (if using a Pro 5R filter), as excess oil can contaminate the sensor. An air leak in the intake system can also cause this light .
• ​Unusual Hissing or Whistling Sounds:​​ These sounds typically indicate an air leak. Carefully inspect all couplings, clamps, and connections in the intake system to ensure they are tight and properly sealed .
• ​Loss of Power or Poor Performance:​​ This can be caused by a severely dirty filter, an air leak, or an obstruction in the intake tube. Inspect, clean, or replace the filter and check the entire system for leaks or blockages .
