BMC offers two types of air filters for certain engine models: Standard and Race. Here's a breakdown of each type:

STANDARD:

• These are standard replacement filters designed for various types of motorcycles.
• The filtering element consists of 4 layers of cotton soaked in low-viscosity oil.
• These filters are already high-performance compared to regular paper filters that come with most vehicles.
• They are suitable for everyday use and provide improved airflow and filtration over stock filters.

RACE:

• BMC Race filters take the concept of increased air flow to an extreme level.
• They achieve this by reducing the number of cotton layers from 4 to 3, which allows even more air to flow through.
• Race filters are recommended exclusively for sports use on the track, as the significantly increased air flow rate can potentially affect carburetion (causing more air to flow than necessary) or fuel injection (where the control unit may struggle to manage the altered air-to-fuel ratio).
• To address this issue, it may be necessary to reconfigure the vehicle's control unit to optimize performance.
• You can identify Race filters by the "race" caption at the bottom of the product code and a yellow line on the filtering element.

In summary, BMC Race filters are engineered for extreme air flow and are best suited for high-performance, track-focused applications. They may require adjustments to the vehicle's control unit to maximize their potential. Standard filters, on the other hand, offer improved performance without the extreme air flow characteristics of the Race filters and are suitable for everyday use.

The CRF is engineered to meet the demands of enthusiasts and professionals seeking top-tier performance from their vehicles or motorcycles.

The Direct Intake Air System (DIA) serves as a junior version of the CDA (Carbon Dynamic Airbox), designed to enhance engine performance by employing similar principles. Here are some key points about the DIA:

1. Performance Improvement: The DIA, like the CDA, is engineered to accelerate the flow of air to the engine at a higher velocity than traditional filtration systems. This optimized air intake contributes to improved engine performance, making it a valuable upgrade for vehicle enthusiasts.
2. Construction: The DIA comprises a plastic air-box with an internal filter. This filter, like all BMC filters, is washable and regenerable. This reusability ensures long-lasting and cost-effective filtration without the need for frequent replacements.

In essence, the DIA offers a more affordable option compared to the CDA while still delivering enhanced engine performance through its advanced air intake design and reusable filter technology.

The primary distinction between the two filtration systems, the CDA and DIA, lies in the material used for their air-box construction:

1. CDA (Carbon Dynamic Airbox): The CDA air-box is entirely constructed from carbon fiber. Carbon fiber is chosen for its exceptional properties, including high resistance to temperature and low thermal conductivity. This material insulates the air filter inside the air-box against engine heat effectively. As a result, cool air from outside the vehicle can directly reach the engine with minimal heat transfer. The Flow Switch in the CDA ensures efficient air conveyance with minimal pressure drop.
2. DIA (Direct Intake Air System): In contrast, the DIA's structure is made of plastic material. While it employs the same air conveyance principle as the CDA, the difference is in the material used for the air-box construction. Plastic, though not as thermally insulating as carbon fiber, still facilitates improved airflow to the engine, enhancing performance.

So, the key distinction is that the CDA uses carbon fiber for its air-box, offering higher resistance to temperature and better insulation against engine heat, while the DIA employs plastic for its air-box construction. Both systems aim to optimize air intake for enhanced engine performance.

OTA is the acronym for Oval Trumpet Airbox.

This is the latest direct intake system made of carbon developed by BMC, an evolution of the well-known CDA.

BMC initially made its mark in the racing world, particularly in Formula1. However, over the past two decades, it has successfully expanded its product range to cater to the Aftermarket sector as well.

BMC occasionally produces filters made of synthetic materials, typically upon specific customer requests. The primary difference between BMC filters made of cotton soaked in oil and filters made of synthetic materials (like plastic sheets) lies in their impurity-stopping principles:

1. Synthetic Filters: Filters made of synthetic materials allow particles to pass through if their size matches the micro holes in the material. For example, a filter with 80-micron holes will allow the passage of all particles smaller than 80 microns, only stopping those particles that are larger than the micro hole. This means that very fine particles, smaller than the hole size, can pass through, including particles like sand, which has dimensions of about 50 microns.
2. Cotton Filters with Oil: BMC's cotton filters, on the other hand, have a larger weave that encourages a high airflow. However, they employ a combination of different layers of low-viscosity oil to effectively trap particles from 7 microns and larger. This means that even very fine particles are captured by the filter due to the oil-soaked cotton, resulting in a more efficient filtration process.

The use of cotton with oil in BMC filters is considered a superior solution, as it combines both effective filtration and enhanced performance, making it a popular choice among automotive enthusiasts and professionals looking for optimal engine protection and power.
