How to Clean S&B Air Filter? A Comprehensive Guide from S&B Filters Expert

Cleaning your S&B air filter is a crucial part of maintaining your vehicle’s performance and extending the life of your engine. The cleaning process involves removing debris, washing the filter with a specialized cleaner, rinsing it thoroughly, and allowing it to dry completely before re-oiling (for oiled filters) and reinstalling.

Why Cleaning Your S&B Air Filter Matters

A clean air filter ensures that your engine receives the proper airflow for optimal combustion. A dirty filter restricts airflow, which can lead to reduced horsepower, decreased fuel economy, and potentially even engine damage over time. Regular filter cleaning allows you to enjoy peak performance and save money on fuel and repairs. Neglecting this crucial maintenance task can prematurely wear out your engine and compromise its efficiency.

Different Types of S&B Air Filters and Cleaning Needs

S&B Filters offers both oiled and dry air filters. Oiled filters, typically constructed with multiple layers of cotton gauze, require re-oiling after cleaning to effectively trap dirt and debris. Dry filters, often made from synthetic materials, don’t need oiling. Understanding which type of filter you have is paramount for selecting the correct cleaning process.

Step-by-Step Guide to Cleaning Your S&B Air Filter

Cleaning your S&B air filter, while straightforward, requires careful attention to detail to ensure its effectiveness is maintained. Here’s a step-by-step guide:

1. Removing the Air Filter

Locate the air filter housing: This is usually a black plastic box located near the engine. Refer to your vehicle’s manual if needed.
Open the housing: Most housings have clips or screws that need to be loosened or removed.
Carefully remove the filter: Take note of its orientation for proper reinstallation.

2. Removing Loose Debris

Tap the filter gently: Tap the filter against a hard surface to dislodge loose dirt and debris.
Use a soft brush: Gently brush away any remaining debris.
Consider compressed air (with caution): If available, use compressed air to blow out any stubborn particles. Hold the nozzle at a distance to avoid damaging the filter material.

3. Washing the Filter (Oiled and Dry Filters)

Use S&B Filter Cleaner: This specialized cleaner is designed to dissolve dirt and grime without harming the filter material. Never use gasoline, kerosene, or strong solvents.
Apply the cleaner liberally: Spray the cleaner onto the entire filter surface, ensuring complete coverage.
Let it soak: Allow the cleaner to soak for 10-15 minutes to loosen the dirt.

4. Rinsing the Filter

Rinse with clean, low-pressure water: Rinse the filter from the inside out, using low-pressure water. This helps to flush out the dirt without forcing it further into the filter media.
Continue rinsing until the water runs clear: Ensure all traces of cleaner and dirt are removed.
Shake off excess water gently: Avoid squeezing or wringing the filter, as this can damage the media.

5. Drying the Filter

Allow the filter to air dry completely: This is the most crucial step. Never use a heat gun or hair dryer, as this can damage the filter material.
Optimal drying time: Depending on the humidity, drying can take anywhere from several hours to overnight. Ensure the filter is bone dry before re-oiling (if applicable).

6. Oiling the Filter (For Oiled Filters Only)

Use S&B Filter Oil: This oil is specifically formulated for S&B air filters and provides optimal filtration. Avoid using other types of oil, as they may damage the filter or reduce its efficiency.
Apply oil evenly: Apply the oil in thin, even coats, working it into the filter pleats.
Let the oil soak in: Allow the oil to soak in for 20-30 minutes, then check for any dry spots. Add more oil as needed. The goal is to have a uniform pink or red color (depending on the oil color) throughout the filter.
Avoid over-oiling: Over-oiling can restrict airflow and cause issues with mass airflow sensors.

7. Reinstalling the Filter

Carefully reinstall the filter: Ensure it is properly seated in the housing, matching the orientation you noted during removal.
Secure the housing: Fasten the clips or screws tightly.
Double-check everything: Ensure the housing is properly sealed to prevent unfiltered air from entering the engine.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to further clarify the process and address common concerns:

Q1: How often should I clean my S&B air filter?

It depends on your driving conditions. In dusty environments, clean it every 10,000-15,000 miles. In cleaner conditions, you can extend this to 20,000-25,000 miles. Regular inspections are recommended.

Q2: Can I use dish soap to clean my S&B air filter?

No. Dish soap can leave residue that attracts dirt and may degrade the filter material over time. Always use S&B Filter Cleaner or a comparable filter cleaner specifically designed for air filters.

Q3: What happens if I over-oil my S&B air filter?

Over-oiling restricts airflow, reducing engine performance. Excess oil can also get sucked into the intake system and contaminate the mass airflow sensor (MAF), leading to engine problems.

Q4: How do I know if I’ve over-oiled my filter?

If your engine is running rough, your fuel economy has decreased, or your MAF sensor is dirty, you may have over-oiled your filter. Visually, the filter may appear overly saturated with oil.

Q5: Can I dry my S&B air filter in the sun?

While the sun can help speed up the drying process, direct sunlight can degrade the filter material over time. It’s best to air dry the filter in a shaded area.

Q6: What are the symptoms of a dirty air filter?

Common symptoms include reduced engine power, decreased fuel economy, black smoke from the exhaust, and difficulty starting the engine.

Q7: Can I use WD-40 to clean my S&B air filter?

Absolutely not. WD-40 is not designed for air filter cleaning and will likely damage the filter material. Stick to approved filter cleaners.

Q8: What if I don’t have S&B Filter Cleaner and Oil?

You can use other high-quality air filter cleaner and oil specifically designed for oiled air filters. Ensure they are compatible with the filter material. However, for optimal results and warranty compliance, S&B products are recommended.

Q9: How can I tell if my S&B air filter is damaged and needs replacing?

Look for tears, holes, or excessive wear and tear in the filter material. If the filter is significantly damaged, it’s best to replace it.

Q10: Does cleaning my air filter void my S&B warranty?

No, cleaning your air filter does not void your S&B warranty, provided you follow the proper cleaning and maintenance procedures outlined by S&B.

Q11: Where can I buy S&B Filter Cleaner and Oil?

S&B Filter Cleaner and Oil can be purchased from authorized S&B dealers, online retailers, and some auto parts stores.

Q12: Are S&B dry filters really maintenance-free?

While S&B dry filters don’t require oiling, they still need periodic cleaning. Follow the same cleaning steps as for oiled filters, skipping the oiling stage.

Conclusion

Maintaining your S&B air filter through regular cleaning is a simple yet highly effective way to maximize your vehicle’s performance, improve fuel economy, and prolong the life of your engine. By following these steps and adhering to the best practices outlined above, you can ensure your S&B air filter continues to provide the clean air your engine needs to thrive. Remember, a clean air filter is a happy engine!
