How to Choose, Maintain, and Maximize the Benefits of S&B Air Filters: A Complete Guide for Engine Enthusiasts​

2025-11-13

If you own a motorcycle, ATV, UTV, or high-performance vehicle and care about engine longevity, power delivery, and cost-effective maintenance, S&B air filters are a smart investment. Unlike generic or paper-based filters, S&B’s synthetic media designs deliver superior airflow, better filtration, and longer service life—all while protecting your engine from dust, debris, and contaminants. This guide breaks down why S&B stands out, how to select the right filter for your vehicle, proper installation techniques, and maintenance best practices to ensure peak performance for years.

Why S&B Air Filters Are a Cut Above the Rest

To understand S&B’s reputation, it helps to start with their core innovation: ​synthetic filter media. Traditional paper filters rely on a rigid, pleated design that traps particles but restricts airflow. Over time, they clog, forcing your engine to work harder and potentially reducing horsepower. S&B flips this script with its proprietary Multi-Fiber synthetic media, a blend of microfibers that creates a maze-like structure. This design allows air to flow more freely (often 20-50% more than stock filters) while capturing 99.9% of dirt, pollen, and road grime as small as 5 microns—smaller than the width of a human hair.

Beyond airflow and filtration, S&B filters are built to last. Where paper filters are single-use, S&B’s washable, reusable design means you can clean and re-oil them dozens of times. For most riders, that translates to 50,000+ miles of use before needing replacement—far longer than the 10,000-20,000 mile lifespan of standard OEM filters. The result? Fewer replacements, lower long-term costs, and consistent engine protection.

S&B’s commitment to quality doesn’t stop there. Every filter undergoes rigorous testing, including ISO 5011 certification (the industry standard for air filter performance) and real-world dust chamber trials. This ensures they meet or exceed OEM specifications while outperforming competitors in airflow and durability.

How to Choose the Right S&B Air Filter for Your Vehicle

Not all S&B filters are created equal—selecting the correct one depends on your vehicle make, model, and specific needs. Here’s how to narrow it down:

1. Confirm Compatibility

Start by verifying your vehicle is compatible with S&B filters. S&B offers filters for motorcycles (Harley-Davidson, Yamaha, Honda, etc.), ATVs/UTVs (Can-Am, Polaris), and even some cars and trucks. Use their online “Fitment Finder” tool on the official website: input your vehicle’s year, make, and model, and it will generate a list of matching filters.

2. Understand Filter Series

S&B’s product line includes several series tailored to different use cases:

  • Pro Series: Their flagship line, designed for high-performance engines and demanding conditions. These feature a thicker synthetic media (4-6 layers) for maximum filtration and airflow, making them ideal for off-road riding, dusty environments, or modified engines.

  • Standard Series: A lighter-duty option for daily commuters or light off-roading. Still far more durable than paper filters, they balance performance and cost.

  • OEM Replacement Series: Designed to directly replace factory filters in vehicles where S&B’s Pro or Standard series aren’t exact fits. These maintain OEM dimensions but upgrade the media to synthetic.

3. Consider Your Environment

If you ride primarily in dry, dusty areas (e.g., deserts, construction zones), prioritize the Pro Series for its enhanced dust-trapping capabilities. For wetter, cleaner environments, the Standard Series may suffice. Always err on the side of a higher-performance filter if you’re unsure—over-filtering is rarely an issue, but under-filtering can lead to engine damage.

Installing Your S&B Air Filter: Step-by-Step Best Practices

Installing an S&B filter is straightforward, but proper technique ensures optimal performance and prevents damage. Follow these steps:

1. Gather Tools and Supplies

You’ll need:

  • Your new S&B filter

  • A clean, well-lit workspace

  • A soft brush or compressed air (low pressure) for cleaning the airbox

  • Disposable gloves (to avoid transferring dirt to the filter)

2. Remove the Old Filter

Open your vehicle’s airbox—this usually involves unscrewing clamps, bolts, or latches. Take note of how the original filter is seated; misalignment is a common cause of leaks. Inspect the airbox interior for dirt or debris; wipe it down with a dry cloth (avoid liquids, which can leave residue).

3. Inspect and Prepare the New Filter

Unpack the S&B filter and check for shipping damage. Hold it up to a light: you should see a uniform pleat structure with no tears or creases. Gently tap it to dislodge any loose fibers.

4. Install the Filter

Place the filter into the airbox, ensuring it sits flush against all sides. Some S&B filters come with a rubber gasket—make sure it compresses evenly to create a tight seal. Reassemble the airbox, tightening clamps or bolts to the manufacturer’s specifications (over-tightening can crack the airbox).

5. Test for Leaks

After installation, start the engine and let it idle. Listen for unusual whistling or hissing—these sounds indicate air leaking around the filter. If you hear leaks, double-check the seal and re-tighten components as needed.

Maintaining Your S&B Air Filter: Extend Its Lifespan and Protect Your Engine

Proper maintenance is critical to getting the most out of your S&B filter. Here’s how to keep it performing at its best:

1. Establish a Cleaning Schedule

Most riders should clean their S&B filter every 3,000-5,000 miles, or more frequently if riding in dusty conditions. For off-road enthusiasts, monthly checks are wise.

2. Clean with the Right Products

Never use soap, water, or harsh chemicals—these can damage the synthetic media. Instead, use S&B’s Air Filter Cleaner, a non-toxic, biodegradable solution formulated to break down dirt without harming the filter. Spray the cleaner onto both sides of the filter, let it soak for 10-15 minutes, then gently agitate with a soft brush to loosen debris.

3. Dry Thoroughly

Rinse the filter with low-pressure compressed air (no more than 10 PSI) to remove loosened dirt, then let it air-dry completely—this takes 2-4 hours. Do not use heat or direct sunlight, as this can warp the media.

4. Re-oil Correctly

Once dry, apply S&B’s Air Filter Oil. Squeeze the bottle in a zigzag pattern across the filter’s pleats, ensuring even coverage. Use a gloved hand to rub the oil into the media—this helps the oil bond with the fibers and trap particles. Aim for a light, uniform sheen; too much oil can restrict airflow, while too little reduces filtration.

5. Inspect for Wear

Every few cleanings, check the filter for tears, holes, or delamination. If you notice damage, replace the filter immediately—even a small tear can let dirt into your engine, leading to costly repairs.

Real-World Benefits: What Riders Are Saying About S&B Filters

Don’t just take our word for it—here’s what actual users report:

  • Increased Horsepower: Many riders note a noticeable boost in throttle response and top-end speed, attributed to improved airflow. One Harley-Davidson Sportster owner measured a 5 HP gain after switching from a stock paper filter to S&B’s Pro Series.

  • Better Fuel Efficiency: Cleaner air allows engines to burn fuel more efficiently. ATVers using S&B filters often see a 2-4 MPG improvement in mixed terrain.

  • Long-Term Savings: A Pro Series filter costs around 70 but lasts 5-7 years with proper maintenance. Compare that to replacing paper filters every 10,000 miles at 20 each—you’ll save hundreds over the filter’s lifespan.

  • Engine Protection: Off-road riders in the Southwest praise S&B’s ability to trap fine desert dust, preventing grit from entering the engine and causing premature wear.
