K&N Engineering Intakes, Air Filters & Performance Filters

What This Brand Covers

K&N Engineering built its reputation on reusable, high flow air filtration. This collection spans complete cold air intake systems, direct fit replacement filters, universal clamp-on filters for custom builds, and maintenance items like oil filters, fuel filters, and cabin filters.

Cold Air Intakes and Intake Systems

K&N Aircharger and NextGen intake kits replace the factory airbox and intake tube with a larger diameter tube and higher flow filter, improving airflow and often adding a stronger intake sound.

Cold Air Intake Systems by Platform

K&N engineers vehicle specific intake kits with tubing, filter placement, and hardware matched to each engine bay rather than a generic universal fit.

Jeep, Dodge, and RAM HEMI Applications

Grand Cherokee SRT8, Dodge Charger and Challenger 5.7L, and RAM 2500/3500 Cummins diesel intake kits are core SKUs, often paired with reusable filters rated for long service life.

Domestic Truck and SUV Applications

Chevy Silverado, Toyota Tundra, Ford F-150, and Chevy Trailblazer SS intake kits round out the domestic truck and SUV side of the lineup for owners chasing more airflow and throttle response.

Reusable and Drop-In Replacement Filters

Many K&N filters use washable, reusable filter media designed for long term service instead of disposable paper elements. Drop-in filters replace the factory filter inside the stock airbox with no other modification needed.

Direct Fit Panel Filters

Panel and oval drop-in filters are sized to match the factory air box exactly, covering applications from Corvette V8 engines to Cadillac CT4/CT5 four cylinder engines.

Universal Clamp-On Filters for Custom Builds

Universal filters are used on fabricated intake tubes, turbo inlets, supercharger setups, and race applications where flange diameter and filter dimensions must be matched by hand.

Matching Flange Size and Filter Shape

Confirm flange diameter, base width, top width, and overall height before ordering a universal filter, since a mismatch will not seal properly against the intake tube.

Oil Filters, Fuel Filters, and Cabin Filters

Beyond intake filtration, K&N makes oil filters, fuel filters for diesel applications, and cabin air filters that service the vehicle HVAC system.

Diesel Truck Filtration

RAM Cummins and Ford Super Duty diesel owners rely on K&N fuel filters and heavy duty intake systems built to handle sustained towing and higher airflow demand.

Filter Cleaning Kits and Maintenance

Reusable K&N filters are designed to be cleaned and re-oiled rather than replaced at every service interval. Cleaning kits and recharge kits support proper long term filter maintenance.

Service Intervals

Dusty roads, off-road use, and towing environments require more frequent filter inspection compared to typical street driven daily use.

Import and European Platform Coverage

This collection also includes intake and filter parts for BMW, Porsche, Toyota, and other import platforms alongside the domestic and Mopar lineup.

Common Questions

What is K&N Engineering known for?

K&N Engineering is known for reusable performance air filters, cold air intake systems, oil filters, cabin filters, fuel filters, and filtration products for cars, trucks, SUVs, and diesel vehicles.

Are K&N air filters reusable?

Many K&N air filters are designed to be washable and reusable when cleaned and serviced according to the product instructions for that specific filter media.

What is the difference between a cold air intake and a replacement filter?

A cold air intake is a complete system that may include a tube, filter, couplers, and heat shield, while a replacement filter is designed to fit inside the existing factory air box.

Do K&N cold air intakes fit every vehicle?

No. Cold air intakes are vehicle specific. Confirm your year, make, model, engine, and trim before ordering to ensure correct fitment.

How do I choose a universal air filter?

Match the flange diameter, filter shape, base width, top width, and height to your intake tube. Universal filters are common in custom builds but must be sized correctly.

Does K&N make filters for diesel trucks?

Yes. This collection includes intake systems and fuel filters for RAM Cummins, Ford Super Duty, and other diesel truck platforms.

Will a K&N intake require a tune?

Most K&N intakes do not require a tune, though some high flow setups on certain platforms may benefit from a supporting tune for optimal results.

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

Service intervals depend on driving conditions. Dusty or off-road environments require more frequent cleaning than typical street driven daily use.

Can I use a K&N cabin filter to improve interior air quality?

Yes. K&N cabin filters are designed to filter interior air passing through the HVAC system, and some models include additional filtration media.

Do K&N products come with a warranty?

Yes. K&N filters and intake systems carry manufacturer warranty coverage, with terms varying by product line.
