Gain an Estimated 44.5-Horsepower for Your 2018 Dodge Challenger Demon 6.2L V8

There’s nothing quite like the sound of a growling, well-fed engine. Help protect the engine of your Dodge Demon and gain a guaranteed increase in horsepower and torque with the K&N® 63-1577 air intake system, engineered specifically for 2018 Dodge Challenger Demon 6.2L V8 models. The K&N® 63-1577 high-density polyethylene (HDPE) intake system boasts an estimated power increase of 44.5-horsepower and 52.3 lb./ft. of torque*, and is protected by K&N’s 10-Year/Million Mile Limited Warranty.

“Easy install, smoothed out the whole system. Instructions were clear and relatively simple. I had previously installed a new cat-back pipe and wasn't completely sold on the sound...the K&N intake helped the engine breathe and actually gave me a rich, deep, smooth tone from the pipes. Noticeable increase in response as well.” – Preston from Delaware [Part No. 63-9039]

WHY CHOOSE A K&N PERFORMANCE AIR INTAKE SYSTEM?

Gain an estimated 44.5-horsepower* with the 63-1577

The 63-1577 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.

“I absolutely love this product. Did not take too long to install and the performance was noticeable. Highly recommended and I will tell all my friends about it.” – Richard from California [Part No. 71-3070]

AERODYNAMIC INTAKE TUBE INCREASES AIRFLOW

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. The 63-1577 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 63-1577 also incorporates a steel heat shield, which helps protect the air filter and intake air from high temperatures within the engine bay.

“Very noticeable difference in performance.” – Matt from Washington [Part No. 63-1568]

HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION

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 63-1577 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.

“As always, top notch quality and excellent fit/finish. Thank you.” – Jacob from California [Part No. 57-3039]

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.
