GET A GUARANTEED INCREASE IN HORSEPOWER

The 63-1581 K&N® cold air intake system offers a guaranteed increase in horsepower and torque for Jeep Wranglers—and features a washable, reusable High-Flow Air Filter™ to help protect against damaging engine contaminants. In addition, a high-density rotationally-molded polyethylene air box helps protect the air filter and intake air from high engine temperatures and directs airflow into the throttle body. The enclosed air box design helps create a barrier against dust, dirt, and moisture.

 

The included intake tube is engineered to flow a high volume of air, and an oiled High-Flow Air Filter™ (also included in the kit) helps increase airflow to your engine—while simultaneously providing exceptional protection from contaminants. The oversized filter shape allows for up to 100,000 miles between cleanings (under normal highway driving conditions). When it 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 intake and filter is designed to last for the life of your vehicle.

DYNAMOMETER RESULTS

K&N® performance air intake systems come with a horsepower guarantee. During dynamometer testing, the 63-1581 provided an estimated power increase of 10.5-horsepower and 10.2 lb./ft. of torque*.

“Very easy product to install. And the power my engine now has is great.” – Roby from Texas [Part No. 63-1529]

CAD-DESIGNED INTAKE TUBE INCREASES AIRFLOW

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler, and therefore more oxygen-dense, often significantly increases engine combustion efficiency. The 63-1581 system features a roto-molded high-density polyethylene (HDPE) intake tube designed to keep airflow to the throttle body smooth and oxygen-dense.

“Noticeable difference. Easy to install. Definitely worth it.” – Scott from Texas [Part No. 63-1564]

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—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.

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.

“Love the throttle response and enhanced turbo sound.” – Robert from Indiana [Part No. 63-2599]

Legal in 49 states. Not legal for sale or use in California on any pollution controlled motor vehicle.

 

*Horsepower gains vary among products and applications, but each K&N performance air intake system is designed to increase airflow efficiency for specific vehicles and their engines. Each kit undergoes significant testing to help ensure that the filter and intake tube are engineered to deliver large increases in airflow and horsepower.
