K&N Engineering
K&N Engineering is the world's leading manufacturer of performance air filters and complete air intake systems.
K&N Premium Performance Gold® Oil Filters

The K&N premium canister type oil filter was originally developed for demanding auto race applications and are designed for durability and easy removal.

The K&N performance oil filter has thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The durable construction will withstand higher oil pressures found only in racing environments without bursting.

The resin impregnated cellulose filter media allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process.

• Drilled safety wire holes for racing in canister oil filters
• Sturdy 1" wrench nut, makes oil filter removal quick and easy
• Heavy-duty construction
• Resin-impregnated filter media provides maximum filtering surface for contaminant removal
• Anti-drainback valve eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown
• Internally lubricated gasket provides positive seal while allowing easy on and off of filter
• Rolled threads provide extra protection against stripping
• Traps 99% of harmful contaminants.
• Ideal for high-end synthetic motor oil

Warranty: K&N Gold oil filters are covered by a limited warranty to be free from defects in materials and workmanship when installed and replaced using engine and equipment manufacturers recommended service intervals.

K&N FilterCharger® Air Filter

The K&N FilterCharger® high performance air filter is designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. The K&N automotive OE (original equipment) replacement air filters generally add 1-4 horsepower.

The high flow cotton gauze air filter is washable, reusable, built to last and consists of four to six sheets of cotton gauze layered between two sheets of aluminum wire mesh. This media is then pleated and oiled to enhance its filtering capabilities and overall performance.

K&N Air Filters were created for an environment requiring maximum horsepower and enhanced acceleration in addition to protection from the dirt and dust of off-road racing. The result is an air filter that allows dramatically more air into an engine, is washable and reusable, and will protect your engine for the life of your vehicle.

• High Air Flow with Excellent Filtration
• Designed to Increase Horsepower and Acceleration
• Washable and Reusable - Filter Care Service Kit Required
• Will NOT Void Vehicle Warranty
• Lasts up to 50,000 miles before cleaning is required depending on driving conditions
• K&N Million Mile Limited Warranty®
• Emissions Legal in all 50 US States.
• Economical, a K&N Air Filter Will Last the Life of Your Automobile, Motorcycle, or ATV
• Works with Original Equipment Manufacturer Vehicle Electronics
• Easy High Performance Add-on
• Environmentally Friendly

The Importance of Oil - A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens.  The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands.  The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection.
***Recharger Filter Care Service Kit Needed for Proper Mantainence (PN 99-5000 or 99-5050)

Engine Protection, Filtration - K&N Air Filter media has been tested both in-house and by independent labs using the ISO5011 test developed by the Society of Automotive Engineers.  In addition K&N tests many of our filters both in and out of the OE airbox ensuring proper fit and function.  K&N's goal is to design filters with the maximum possible airflow achievable while providing guaranteed engine protection.

K&N Million Mile Limited Warranty®: K&N O/E Replacement Air Filters and Air Intake Systems are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.

K&N 57 Series Generation II Air Intake Kit (FIPK's)

The K&N 57 Series Generation II Air Intake Kit (FIPK's) represents a dramatic improvement over a K&N OE replacement filter alone; using only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube.

The 57 Series Generation II Air Intake Kit eliminates air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into added HORSEPOWER

The K&N 57 Series kit uses the largest conical shaped high-flow air filter that can fit into the engine compartment while utilizing the factory holes and mounting points. The extra filter size provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box.

When possible, the air filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. The air filter is attached to a rotationally molded tube made from interlaced High Density Polyethylene (HDPE). This process allows us to precisely shape the tube to reduce turbulence and accelerate airflow into the engine. The intake tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life.

• Guaranteed to Provide more HP and Increased Acceleration
• Engineered to Specific Vehicle Design
• Easy to Install, Usually in 90 minutes or less!
• Lasts up to 100,000 Miles Before Service is Required (depending on driving conditions)
• Million Mile Limited Warranty
• Replaces OEM Filter and Air Box
• Air Filter is Washable and Reusable
• Works with Original Equipment Manufacturer Computer Systems
• Designed to use Factory Holes & Mounting Points Whenever Possible
• Requires Recharger Filter Care Service Kit (99-5050) for cleaning and maintenance.
• CARB Exempt and street legal in all 50 US States

NOTE: Some FIPK's will not fit on vehicles with lift kits.

K&N 57i Performance Induction Kit
NOT Legal for Use in California

When you bolt-on a 57i intake, you will notice the difference the next time you drive your vehicle. The 57i Generation I Intake Kit is a great way and in many cases the only way to maximize airflow and engine performance. The 57i intake kit will replace the factory air box providing both High-Flow air filter technology and a larger air filter size.

57i Series Intake Kit will free your car from the size restriction that comes with the factory air box and will provide power throughout the RPM range. This intake kit brings engine airflow out of the factory box by providing a large size open-air conical or round High-Flow Air Filter. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N OE replacement filter which is always limited to the size of the factory air box. The air filter is then either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adaptors are made from high quality materials such as steel, aluminum, silicon or reinforced nylon and ensure long life.

• Designed to Increase HP and Acceleration
• Engineered to Specific Vehicle Design
• Easy to Install, Usually in 90 minutes or less!
• Lasts up to 100,000 Miles Before Service is Required (depending on driving conditions)
