New K&N Intake for 2017-2018 Subaru Impreza & 2018-2019 Crosstrek

The 2018 Subaru Impreza is known for standard all-wheel drive—a feature unavailable on nearly every other compact car—but also boasts excellent gas mileage (28 mpg city/38 mpg highway). An IIHS Top Safety Pick+, safety features abound on this vehicle—including Subaru’s Eyesight system, rear cross traffic alerts, blind spot monitoring, automatic emergency braking, and more.

The 2018 Subaru Crosstrek also comes standard with all-wheel drive, and has been fully redesigned for the 2018 model year. One distinct feature is an abundance of cargo space, making the Crosstrek an excellent choice for weekend trips—and you also get a towing capacity of up to 1,500 pounds, which is excellent for its class. The same 152-horsepower 2.0L engine appears on both the Impreza and Crosstrek.

The 2018 Impreza and Crosstrek 2.0L engine offers 152-horsepower at 6,000 RPMs—but power-minded Subaru drivers can gain a guaranteed increase in horsepower with the 69-8010TTK air intake system—engineered specifically for 2017-2018 Subaru Impreza and 2018-2019 Subaru Crosstrek 2.0L models. The K&N® 69-8010TTK high-density polyethylene (HDPE) intake system boasts an estimated power increase of 5.22-horsepower and 3.61 lb./ft. of torque* and improved engine sound. The new K&N® filter and air box are relocated from the factory air box location to a lower location nearer the fender, which helps provide the filter with a higher volume of cool air.

“Just installed this cold air intake on my 2017 Subaru Impreza Limited 2.0....and it has greatly enhanced the car's performance, gas mileage, AND the sound is fantastic.” – Dan from Florida [Part No. 69-8010TTK]

The 69-8010TTK is designed to help keep engine air cooler, which can increase engine combustion efficiency, and helps provide a smooth, low-restriction path for airflow to the engine. Your engine needs oxygen to create power; the cylinders in your vehicle’s engine need to have air to create the explosion that produces horsepower and torque. Since cold air contains more oxygen molecules than warm air, injecting a higher volume of oxygen-rich air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.

In a typical stock air intake system, air has to pass through a thick, disposable paper filter, and then move through a narrow system of tubing that can cause air to swirl and become turbulent. Excess turbulence causes the molecules within the air to collide, creating heat, which lowers the density of the air and reduces the efficiency of combustion. All K&N intake systems are specifically engineered to help keep your engine air cooler.

“Easy to install. Really opened up air flow from stock. More responsive and made my exhaust louder which is what I was looking for.” – Joseph from Massachusetts [Part No. 63-3082]

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. The 69-8010TTK intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to reduce turbulence in the air, and helps keep engine air cooler for increased engine performance! The 69-8010TTK also incorporates a steel heat shield, which helps protect the air filter and intake air from high temperatures within the engine bay.

“Great experience, ordering and delivery were seamless. Install was a breeze and the product is awesome.” – Mike from Washington [Part No. 77-2579KTK]

High-density polyethylene (HDPE) has a very high strength-to-density ratio, as well as the ability to withstand extremely high temperatures—making it an excellent choice for the environment in the engine bay. HDPE can also be molded into custom shapes, allowing it to be adapted for specialized tubing designs.

Factory intake systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow, create turbulence, and muffle engine noise—unlike K&N intake systems, which are designed to give your engine a more satisfying growl on acceleration, but return to quiet once at speed.

Under normal circumstances, most automotive air filters demonstrate an inverse relationship between airflow and efficiency—the higher the airflow, the less efficient the air filter is at protecting the engine, and vice versa. The oiled design of K&N air filters assists in “absorbing” dirt particles—and in turn helps incorporate those particles into the filter surface itself, which helps maintain the filter’s efficiency and ability to flow air. When tiny particles are captured and saturated with oil, they in turn can become tacky, allowing them to capture other particles.

The High-Flow Air Filter™ included in the 69-8010TTK intake kit is oversized with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters feature an oiled, layered design.

When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle.

Maintaining the proper air-to-fuel ratio (AFR) is critical for engine performance, and relates to the amount of air versus the amount of fuel used by an engine for combustion. A correct, stoichiometrically balanced AFR produces combustion with perfect efficiency, excluding other factors. For gasoline engines, the theoretically perfect chemical ratio is 14.7:1—14.7 parts air to one part fuel. In effect, this means that an engine requires almost fifteen times more air than fuel for efficient combustion—which emphasizes the importance of providing a high volume of air through an intake system.

The K&N 69-8010TTK intake system is engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit.

Each intake system comes with a 10-Year/Million Mile Limited Warranty. Furthermore, using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.
