What is a BMC Air Filter?
BMC is an Italian company specializing in the production of high-quality air filters for automotive applications. Founded in 1996, BMC has established a reputation for innovation and excellence in the industry. The core product, the BMC air filter, is a washable and reusable filter that replaces the stock paper filter in a vehicle's air intake system. It is constructed from a layered cotton gauze material, which is oiled to enhance its filtration capabilities. This design allows for a significant increase in airflow while effectively trapping dust, dirt, and other contaminants. The primary advantage of a BMC air filter over conventional filters is its ability to maintain optimal engine performance over a long period without the need for frequent replacements. This makes it an environmentally friendly and economical choice.
How an Air Filter Works in a Vehicle
To appreciate the value of a BMC air filter, it is essential to understand the role of an air filter in a vehicle. The internal combustion engine requires a precise mixture of air and fuel to operate efficiently. The air intake system draws in outside air, which must be clean and free of particulates. The air filter's job is to prevent harmful debris from entering the engine. If contaminants like dust or sand reach the engine cylinders, they can cause abrasion and damage to critical components, resulting in reduced performance and potential engine failure. A standard paper filter works by trapping particles in its fibrous material, but over time, it can become clogged, restricting airflow and forcing the engine to work harder. A high-performance filter like those from BMC is designed to offer less resistance to airflow, allowing the engine to breathe more easily, which translates to better combustion and improved power output.
Key Benefits of Using a BMC Air Filter
The decision to switch to a BMC air filter comes with several tangible benefits. First, increased horsepower and torque are common results. Because the filter provides less restrictive airflow, the engine can intake more air, leading to a more complete burn of the fuel. This can result in a noticeable gain in power, especially in high-revving or turbocharged engines. Second, improved fuel economy is another significant advantage. With better airflow, the engine operates more efficiently, often requiring less fuel to produce the same amount of power. Over time, this can lead to substantial savings at the gas pump. Third, the reusable nature of the BMC filter makes it cost-effective. While the initial purchase price is higher than a disposable paper filter, the ability to clean and reuse it multiple times means you avoid the recurring cost of replacements. A single BMC filter can last for the entire life of the vehicle if properly maintained. Fourth, superior filtration is a hallmark of BMC products. The cotton gauze material, combined with a special filtering oil, captures a higher percentage of fine particles than many standard filters, providing better protection for your engine. Finally, environmental friendliness is a key benefit. By reducing waste from discarded paper filters, you contribute to less environmental impact.
Types of BMC Air Filters
BMC offers a range of air filters to suit different vehicles and applications. The most common type is the panel air filter, which is designed to replace the standard rectangular or panel-shaped filter found in most modern cars with stock air intake systems. This is a direct drop-in replacement that requires no modification to the vehicle. Another popular type is the cone air filter or universal air filter. These are typically used in performance applications or when an aftermarket cold air intake system is installed. Cone filters are shaped like a cone and are often larger, providing an even greater increase in airflow. They are universal in fit but require proper sizing and installation. BMC also produces specific application filters for high-performance vehicles, motorcycles, and even motorsports. Each filter is engineered to meet the specific airflow requirements of the vehicle model, ensuring optimal performance gains. When selecting a BMC air filter, it is crucial to choose the correct type and size for your vehicle to achieve the best results.

Step-by-Step Guide to Installing a BMC Air Filter
Installing a BMC air filter is a straightforward process that most vehicle owners can perform themselves with basic tools. Always refer to your vehicle's owner's manual for specific instructions and safety precautions. Before starting, ensure the engine is cool to avoid burns. Here is a general guide for replacing a standard panel filter with a BMC panel filter. First, locate the airbox. In most vehicles, the airbox is a plastic box connected to the engine via a large hose. It is usually found near the front of the engine bay. Second, open the airbox. This typically involves unclipping metal clips or unscrewing a few screws. Use a screwdriver or your hands as needed. Be careful not to force it open, as the clips can be fragile. Third, remove the old air filter. Take out the disposable paper filter and inspect the airbox for any accumulated debris. Clean the interior of the airbox with a damp cloth to remove dust and dirt. Fourth, insert the new BMC air filter. Place it in the same orientation as the old filter. Ensure it sits snugly and evenly in the housing. The BMC filter is a direct fit, so it should drop in without issues. Fifth, close the airbox. Securely fasten the clips or screws to create an airtight seal. A poor seal can allow dirty air to bypass the filter. Finally, start the engine and listen for any unusual noises. Take a short test drive to confirm everything is functioning correctly. For cone filters, the installation may involve removing the entire airbox and connecting the filter directly to the intake tube, following the instructions provided with the filter or cold air intake kit.
Maintenance and Cleaning of a BMC Air Filter
Proper maintenance is crucial for the longevity and performance of a BMC air filter. Unlike disposable filters, a BMC filter requires periodic cleaning and re-oiling. The frequency of cleaning depends on driving conditions. For normal street use, cleaning every 15,000 to 30,000 miles is recommended. If you drive in dusty or polluted areas, clean it more often, such as every 5,000 miles. BMC sells a dedicated cleaning kit that includes a cleaner solution and filter oil. Here is the detailed cleaning procedure. First, remove the filter from the vehicle following the installation steps in reverse. Second, clean the filter by gently tapping it to dislodge loose dirt. Then, spray the BMC cleaner evenly over the entire surface, including the pleats. Allow it to soak for 10-15 minutes. Do not use harsh chemicals or gasoline, as they can damage the filter material. Third, rinse the filter with low-pressure water from the clean side (inner side) to the dirty side (outer side) to push contaminants out. Use cool or lukewarm water; avoid high-pressure water jets that can distort the cotton layers. Fourth, let the filter dry naturally. Place it in a well-ventilated area away from direct heat or sunlight. It may take several hours to dry completely. Do not use compressed air or a hair dryer, as this can cause damage. Fifth, apply filter oil. Once dry, apply the BMC filter oil evenly across the outer surface. The oil is essential for trapping particles; without it, the filter will not work effectively. Use your hands or a applicator to spread a thin, uniform layer. The filter should be lightly coated but not dripping. Sixth, reinstall the filter once the oil has set for about 20 minutes. Proper maintenance ensures the filter continues to provide excellent filtration and airflow.
