K&N Engineering Intakes, Air Filters & Performance Filters

Shop K&N Engineering cold-air intakes, performance air filters, oil filters, cabin filters, universal filters, filter wraps, cleaning kits, and intake accessories at Black Ops Auto Works. The complete K&N collection covers cars, trucks, SUVs, diesel vehicles, motorcycles, ATVs, UTVs, marine engines, industrial equipment, racing applications, and custom intake systems.

K&N Cold-Air Intake Systems

K&N AirCharger, NextGen, Typhoon, and other performance intake systems replace selected factory airbox, filter, and intake-tube components. Depending on the application, a system may include a molded or metal intake tube, heat shield or enclosed airbox, washable filter, couplers, clamps, brackets, mounting hardware, and provisions for factory sensors or ventilation connections.

K&N tests vehicle-specific intake systems and publishes dyno information for individual part numbers. Horsepower, torque, sound, and airflow results are application-specific. Use the test data for the exact K&N part number rather than assuming every intake produces the same result.

Washable K&N High-Flow Air Filters

K&N High-Flow replacement filters are designed to fit inside compatible factory airboxes. Many use layered cotton-gauze media treated with filter oil and are washable and reusable when maintained according to K&N instructions. Available configurations include panel, round, oval, cylindrical, conical, and application-specific shapes.

Not every K&N product uses washable cotton-gauze media. Check the filter line, material, washable specification, cleaning instructions, and required service products before attempting to clean or oil any filter.

K&N Advantage and Advantage Plus Filters

K&N Advantage and Advantage Plus products provide disposable replacement-filter options for supported vehicles. These filters are different from K&N’s washable High-Flow line and should be replaced according to their product specifications and operating conditions.

Do not wash, oil, or service a disposable filter unless its instructions expressly permit that procedure. Dust exposure, construction environments, off-road driving, towing, and other severe conditions can require more frequent inspection or replacement.

Universal and Custom Air Filters

K&N universal clamp-on filters support custom intake systems, racing applications, fabrication projects, and equipment without a vehicle-specific drop-in filter. Choosing a universal filter requires more than matching the flange diameter. Confirm flange inside diameter, flange angle, flange length, filter height, base dimensions, top dimensions, overall shape, available clearance, airflow direction, and mounting support.

A universal filter should not carry the weight of unsupported intake tubing. Secure the intake assembly correctly and provide clearance from belts, fans, exhaust components, sharp edges, bodywork, and moving engine parts.

K&N Oil Filters

K&N oil filters are available in spin-on and cartridge configurations for automotive, powersports, off-road, marine, and other supported applications. K&N offers multiple oil-filter lines with different canister designs, removal features, media, and service specifications.

Select an oil filter by the exact vehicle or equipment application and K&N part number. Thread size, sealing-gasket dimensions, bypass-valve specification, anti-drainback requirements, canister clearance, and cartridge dimensions must all match. Follow the engine manufacturer’s oil type, capacity, installation, and service-interval requirements.

K&N Cabin Air Filters

K&N cabin-filter options include washable reusable filters and extended-life disposable products. Cabin filters help capture contaminants from air entering the passenger compartment through the heating and ventilation system. Some disposable designs use activated carbon for added odor control.

Cabin-filter fitment can vary by model year, trim, HVAC housing, and vehicle production date. Confirm the exact application and airflow direction during installation. Engine air-filter cleaner and oil must never be applied to a cabin filter unless the cabin-filter instructions specifically call for the appropriate K&N cabin-care products.

Powersports, Marine, Racing, and Industrial Filters

The K&N catalog extends beyond passenger vehicles. This collection includes replacement and universal filters for motorcycles, ATVs, UTVs, marine engines, racing air cleaners, agricultural equipment, construction machinery, and industrial engines. Similar dimensions do not guarantee compatibility with the equipment’s housing, airflow demand, operating environment, or mounting system.

Use the equipment model, engine information, original filter reference, K&N cross-reference, and complete dimensions when selecting these specialized filters.

PreCharger and DryCharger Filter Wraps

K&N PreCharger and DryCharger wraps cover compatible filter shapes to provide an additional barrier against selected debris or moisture exposure. Each wrap is sized for a particular filter or dimensional range. A filter wrap does not make an intake waterproof and does not authorize water crossings beyond the vehicle or intake manufacturer’s limits.

K&N Filter Cleaning and Maintenance

Washable K&N filters require the cleaner, drying procedure, and oil quantity specified for their particular media. Applying too much oil, using compressed air, exposing the media to excessive heat, or cleaning it with an unapproved chemical can damage the filter or affect operation.

Inspect filters according to actual operating conditions. Follow the service instructions for the exact part number rather than using one universal mileage interval across street, diesel, off-road, racing, marine, and industrial applications.

How to Choose the Correct K&N Product

  • Confirm the exact year, make, model, engine, trim, and drivetrain.
  • Match the complete K&N manufacturer part number.
  • Determine whether the filter is washable, disposable, oiled, or dry.
  • Verify dimensions, flange size, shape, quantity, and available clearance.
  • Check sensor, ventilation, emissions, and factory-airbox compatibility.
  • Review included intake hardware and required installation components.
  • Use product-specific dyno data for performance claims.
  • Follow the exact cleaning, oiling, and service instructions.

Frequently Asked Questions

Are all K&N air filters washable and reusable?

No. Many K&N High-Flow filters are washable, but Advantage, Advantage Plus, oil-filter, and other product lines may be disposable. Check the exact product specifications.

Do K&N intake systems require tuning?

Requirements vary by vehicle and intake. Review the product page and installation instructions for tuning, emissions, fuel, and sensor requirements.

How often should I clean a K&N air filter?

Use the service guidance for the exact filter and inspect it according to driving conditions. Dusty, off-road, racing, and industrial environments can require earlier attention.

Can I choose a universal filter by flange size alone?

No. Confirm flange angle and length, overall filter dimensions, available clearance, airflow requirements, and mounting support.

Does every K&N product have the same warranty?

No. Coverage varies by product category, use, maintenance, and installation. Review the current warranty terms for the exact product.
