Direct Induction Filter Options

BMC Conical Air Filters

BMC conical air filters are specialized direct-induction filter options for custom intake setups, carburetor applications, engine breather use, and select vehicle-specific kits. Unlike a standard replacement filter that fits inside the original airbox, a conical filter is typically selected by size, airflow design, flange dimensions, and application requirements.

Because conical filters are highly fitment-specific, European Performance Filters recommends confirming the correct BMC filter before ordering. Many conical filters are special-order items, so sizing, availability, and lead time should be checked before purchase.

Built for Custom Intake Applications

Conical filters are not one-size-fits-all parts. The correct filter depends on the intake layout, available space, flange size, airflow needs, and whether the vehicle uses a custom intake, carburetor, breather, or specific BMC kit.

  • TW Twin Air filter options
  • Carburetor and breather filters
  • Special-order fitment support
Conical Filter Types

BMC Conical Filter Options

BMC conical filters are available in multiple formats depending on the airflow path and application. The correct choice depends on sizing, installation style, and the intake system being used.

1

SA Single Air Filters

SA conical filters use a single lateral airflow design. These are commonly considered when a direct-induction conical filter is needed and the required dimensions match the intake setup.

2

TW Twin Air Filters

TW conical filters use both lateral and central airflow. These may be selected for applications where the intake design benefits from the Twin Air construction and the fitment dimensions are correct.

3

Specialty Filter Uses

BMC also offers conical-related options such as carburetor filters, engine breather filters, and specific kits for certain applications where a ready-to-install solution is available.

Conical Filters vs CDA Intakes vs Replacement Filters

Conical filters, CDA intake systems, and replacement filters all serve different needs. Choosing the wrong category is how people end up staring at a filter that almost fits. Almost is expensive.

BMC Product Type Best For What to Know Next Step

CDA Intake Systems Drivers looking for an enclosed BMC carbon dynamic airbox system CDA systems are enclosed intake systems, not the same as open conical filters. Shop CDA Intakes
BMC Replacement Filters Drivers and riders who want a washable filter for the factory airbox The easiest BMC upgrade for most vehicles because the filter is designed to fit the original airbox. Shop Car Filters
Motorcycle Filters Motorcycle riders looking for standard or race BMC filter options Most riders should start with the motorcycle filter collection unless they need a specific conical or CRF application. Shop Motorcycle Filters
Before You Order

Conical Filter Fitment Depends on Measurements

A conical filter is often chosen by physical dimensions, not just year, make, and model. Flange inside diameter, base outside diameter, top outside diameter, filter height, flange length, and available engine bay space can all matter.

If you are replacing an existing conical filter, building a custom intake, fitting a carburetor filter, or looking for a BMC breather filter, send EPF the details before ordering. The better the measurements, the better the chance of getting the correct filter the first time.

  • Flange inside diameter
  • Base and top outside diameter
  • Filter height and available clearance
  • Current filter part number if available
  • Vehicle, engine, and intake setup details

Special-Order Expectations

Many BMC conical filters are special-order items. If a conical filter needs to be specially ordered, payment is typically due up front and the item may take 6–8 weeks to receive.

Simple rule: if you do not already know the exact BMC conical filter part number, contact EPF first. These are not the parts to guess on.

Conical Filter Questions

BMC Conical Air Filter FAQ

Quick answers for customers comparing BMC conical filters, CDA intake systems, and standard replacement filters.

What is a BMC conical air filter?

A BMC conical air filter is a direct-induction-style filter option used for custom intake setups, carburetor applications, engine breather use, or specific kits where the original airbox is not being used in the same way as a standard replacement filter.

What is the difference between SA and TW conical filters?

SA stands for Single Air and uses a lateral airflow design. TW stands for Twin Air and uses both lateral and central airflow. The right choice depends on the intake setup and correct filter dimensions.

Are BMC conical filters special order?

Many BMC conical filters are special-order items. If a filter needs to be specially ordered, payment is typically due up front and the item may take 6–8 weeks to receive.

Should I choose a conical filter or a CDA intake?

Choose a conical filter when your setup requires a properly sized direct-induction filter. Choose a CDA intake if you are looking for an enclosed BMC carbon dynamic airbox system and your application supports it.
