Why a KN Cold Air Intake is a Great Choice

How Does a Cold Air Intake Work and Why Should I Replace the One That Came With My Vehicle?

In a standard air intake system, air passes through a disposable paper filter and then flows into the engine through a complex system of tubing. K&N cold air intake systems provide a less restrictive path for airflow, increasing the volume of cool, oxygen-rich air into your engine. A performance air filter is paired with specially designed tubing and a custom air box or heat shield (engineered to protect the intake air from the heat of the engine), which in combination deliver a guaranteed increase in horsepower and torque.

Legendary K&N Quality & Reliability

K&N Cold Air Intake Guaranteed to Increase Horsepower and Torque

K&N Intake Kit Provides More Engine Growl

K&N Cold Air Intake System Proudly Made in the USA

Increased Horsepower & Torque- Guaranteed

Yes, K&N intakes really do increase horsepower and torque; in fact, it's guaranteed. Each intake kit undergoes significant testing to help ensure that the air filter and intake tube are positioned to deliver large increases in airflow and horsepower.

Less Restriction = More Engine Growl

By removing excess stock baffles, you get to enjoy a satisfying engine growl on acceleration that returns to quiet once at speed. The amount of growl is all in your hands… or should we say feet. Growl while accelerating on the open road and return to quiet as you drive through your neighborhood.

Proudly Made in the USA

K&N products are designed and manufactured on-site, and all of our Cold Air Intakes are made in the USA. K&N is headquartered in Riverside, California, and also operates facilities in Grand Prairie, Texas. Our US based, knowledgeable customer support staff is available to assist you with any questions or concerns.

K&N Engine Air Filter- Nothing Beats the Original

No Substitution for the Original- The Difference a K&N Filter Makes in Your Vehicle

Increased performance starts with K&N’s reusable, air filter, which combines layers of pleated, breathable cotton with K&N’s signature red filter oil. Paper air filters, while efficient, can become quickly clogged as their pores fill with dirt and debris. K&N’s oiled cotton filter absorbs dirt and dust particles rather than physically blocking them. The tacky, oiled particles that collect in the filter become an asset to the filtration rather than an obstacle, capturing new particles entering the system while still allowing a high volume of airflow to pass through. This allows clean air to continue flowing into your engine.

Unlike disposable paper filters, which typically last for 12-15,000 miles before they must be replaced, the high-performance K&N filter included with your intake can go up to 75,000 miles before needing to be cleaned (under normal driving conditions).

K&N Cold Air Intakes- Frequently Asked Questions

K&N Intakes In House Dyno Testing

K&N Intake System Engine Protection

K&N Intake System Rotomolded and Aluminum Tube

K&N CAI Heat Shield and Enclosed Air Box

Why is Dyno Testing Important & How Can I Tell if It’s Accurate?

K&N's air intake horsepower/torque testing is performed at our in-house facilities in Riverside, CA on wheel-based dynamometers and help provide a power estimate that is likely to more closely reflect real-world conditions than an engine-based dynamometer. K&N’s standard testing is designed to measure relative power differences on a vehicle with and without K&N products installed, and SAE (Society of Automotive Engineers) correction factors are utilized to help ensure accuracy. If you notice horsepower claims from other manufacturers that seem too good to be true, we encourage you to do your own research. Check the dynamometer reports for vehicles, dates tested, and if correction factors are used.

How Does a K&N Intake Protect Your Engine?

Most disposable paper filters create a large amount of airflow restriction, as the openings in the filter media have to be extremely small to filter efficiently—which slows airflow. Because dust accumulates on the surface of the disposable filter and blocks the openings in the media, the filter will typically become increasingly more restrictive to airflow over time. Conversely, K&N oiled filters are engineered to become more efficient over their recommended service life as dirt and contaminants are integrated into the filter media, while still allowing a high volume of air through to the system. This allows you to continue to get the performance you expect from your K&N intake, while also being able to rely on the cutting-edge efficiency and protection that a K&N oiled air filter provides.

What's the Difference Between a Roto-Molded and an Aluminum Intake Tube?

Both a Roto-Molded and an Aluminum Intake Tube from K&N provide the same increase of air flow to your engine. It all comes down to how you want it to look in your vehicle. If you enjoy a more custom look under the hood, the Aluminum Tube is a great choice.

What Does the Heat Shield Do and Is That Better Than a Closed Air Box?

Both the custom heat shield and HDPE air box help protect the incoming air from the heat of your engine. They both have unique features and which one you choose is a personal preference based on those features. High-performance drivers may want an open filter element and heat shield for even greater airflow. Off-roaders may prefer an intake system with a custom air box, which helps protect against dust, dirt, and moisture and offers additional filter protection from extremely dirty environments or water crossings. Options with an enclosed air box give you the freedom to adventure while offering easy access to the air filter for quick cleaning and maintenance — no special tools required.

KN Intakes are Easy to Install

Easy to Install

Installing an intake kit might seem intimidating, especially if it's your first DIY car modification, but thankfully you don't have to be a seasoned mechanic to successfully install a cold air intake yourself. While every kit is slightly different (since they are designed to be a perfect fit in the engine bay of specific year/make/models), installation can typically be completed in 60 minutes or less and requires only simple hand tools. Detailed, step-by-step instructions are included with each kit.

Tools Typically Needed for Installation

  • Ratchet
  • Extension
  • 10mm socket & 14mm socket
  • Allen key
  • Flat blade screwdriver
  • Phillips screwdriver
  • 10mm wrench
  • Pliers

How does the K&N 57-2530 increase horsepower? By eliminating airflow obstruction in your engine. Restriction of air flow between an air filter and an engine robs even the most powerful engine of horsepower. K&N air intake kits virtually eliminate air path restriction by replacing the standard air filter and the entire air path to the engine. The aerodynamically engineered conduit that makes up the 57-2530 drives a massive amount of air into an engine, which translates into power. This conduit begins with an oversized conical high-flow air filter. This larger filter can fit into the engine compartment using factory holes and mounting points because the K&N 57-2530 replaces your stock intake tube, and air box. This provides more airflow at lower restriction than a standard filter, limited by the size of the factory air box. The oversize air filter also captures and holds more dirt, increasing the service life before a cleaning is required (up to 100,000 miles). The filter is also isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower.

The filter attaches to a rotationally molded tube made from nonmetallic interlaced high density polyethylene (HDPE). This allows for precision shaping of the tube to reduce turbulence and accelerate airflow into the engine. This is why some K&N tubes have unique shapes or indentations that are specifically engineered for each engine configuration. Finally, the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today.

Street Legal
Many K&N intake systems are street legal in all 50 states and include a California Air Resource Board (CARB) Executive Order (EO) number that ensures the kit has been tested to comply with emissions standards. EO numbers apply to the kit as well as the year, make and model it is being installed on. Systems with no EO number are street legal in most states but may not be used on emissions controlled vehicles in the state of California or other states adopting California emission standards. Consult K&N's website to search by part to see which cold air intakes are CARB exempt for which vehicles.
