A free-flowing HDPE intake tube helps keep engine air cooler

HDPE INTAKE TUBE INCREASES AIRFLOW

The 57-3087 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to provide a smooth path for airflow and a higher volume of air to the engine. The 57-3087 also incorporates a steel heat shield, which helps protect the air filter and intake air from high temperatures within the engine bay.

“Great fit and notice horsepower improvement.” – Larry from Washington [Part No. 57-3034]

WHAT ARE THE BENEFITS OF HIGH-DENSITY POLYETHYLENE (HDPE) INTAKE TUBES?

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.

IMPROVE ENGINE SOUND

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

A performance air filter helps protect your engine from contaminants

HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION

The High-Flow Air Filter™ included in the 57-3087 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—providing up to 50% more airflow than a traditional paper filter. 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.

INSTALLATION

The K&N 57-3087 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.

WARRANTY

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.

“Outstanding and a very awesome product.” – David from Indiana [Part No. 57-2554]

“Love it, was super easy to install and makes big difference around the 3-4 thousand range.” – Shawn from Canada [Part No. 57-2575]
