    Remarkable Cooling and Power Increase. Enjoy cooler, cleaner, and more powerful engine with the K&N Series 63 AirCharger Cold Air Intake. It’s all you need to keep your engine running smoothly while gaining as much as 12.50 horsepower at 4,630 RPM. It replaces your Wrangler's restrictive air intake to allow for even more cold air to provide superb cooling to the engine while keeping it safe from the damaging effects of dust and debris.

    No Tuning Required. This air intake has been precision-built using computer-aided technology. It increases your Jeep’s power using its stock tune to eliminate the need for custom tuning after installation. However, ExtremeTerrain highly recommends recalibrating its onboard ECU to get the best possible performance from this air intake.

    High-Quality Air Filter. This air intake features a conical air filter with a bigger surface area and dust capacity. It is made out of high-quality cotton gauze material and has been proven to capture more dust and debris to help keep your engine running smoothly for hundreds of thousands of miles more.

    Durable Roto-Molded Air Box. This cold air intake maximizes airflow with its high-quality, roto-molded air box. It has been designed to guarantee increased air intake to deliver superb cooling action that greatly enhances your engine’s performance. And with its black powder coated finish, the air box adds stunning appeal to your Wrangler's engine bay.

    Bolt-On Design. This cold air intake installs in about 90 minutes or less. It uses the factory mounting points on your Jeep’s engine bay without the need for any modifications.

    Backed by a Million-Mile/10-Year Warranty. The Series 63 AirCharger Cold Air Intake is guaranteed by a million-mile or 10-year warranty, whichever comes first, against defects in material or workmanship. Some conditions may apply.

    Not CARB Certified. This K&N Series 63 AirCharger Cold Air Intake is not CARB certified at this time. It may not be sold or used in California or other states where California emission regulations are adopted.

    Application. This K&N Series 63 AirCharger Cold Air Intake is designed for all 2018-2019 Jeep Wrangler JL 3.6L models.

    Technical Note. The K&N Cold Air Intake is not designed for vehicles equipped with a Body Lift.

        2 Top Rated Questions

        Does this affect the factory warranty?

        What does a tune mean? Can you do that with a Tazer? Or do you have to have it professionally tuned? What exactly is being changed to improve performance in the computer?

        • The tune being referenced is not necessarily a custom tune, no. A standard pre-loaded tuner would indeed enhance this cold air intake, just like it would enhance an otherwise stock Mustang. When it comes to custom tunes, custom tunes will be better than a preloaded tune, however a custom tune is only required when a product is advertised with a tuning being required.

            Great mod for manual trans

            Very easy to install. I purchased this primarily for more engine noise, these motors are so quiet shift point are hard to hear. I’m not one to look at the tach for shifting and would prefer sound. It does appear I may be getting a bonus mpg small increase as well.

            everything I expected

            No gas mileage improvement, but love having it anyway. Faster throttle response time for sure.

            Already seeing a MPG improvement!

            Install was moderately difficult. Like the tone of the engine at acceleration. Seeing 1.5 mpg improvement in a week.

            Easy install

            Pretty simple install. Stinks you have too remove front grill to get out factory intake. I will update performance after use for awhile.
