MAXIMUM PERFORMANCE
Our cold air intake for the 2018 Jeep Wrangler JL was engineered to minimize air restriction and flows 26.18% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out unwanted engine heat.





PREMIUM SILICONE RUBBER
The air filter, couplers, inlet, and tube seal are made from premium silicone rubber. Silicone won't crack, has exceptional tear strength, and can handle temperatures as high as 400F. Demand Better. Demand S&B.





NO CHECK ENGINE LIGHTS
S&B devotes a huge amount of resources to engineer our intakes that allow your engine to run properly with stock calibration or enhanced tuning. The JL intake utilizes your stock air temperature sensor and features an aluminum CNC lathed crankcase breather connection, that ensures perfect snap-on fitment.





OEM FIT AND FINISH
Featuring a fully enclosed one-piece box design. The lower box prongs integrate with the OEM mounting locations to ensure a perfect fit. The Silicone Fender Seal is designed to pull air from the stock location and retains the use of the stock ram air tube.



This kit comes with a massive, highly-efficient air filter which results in better performance and protects your engine. Available in either 8-layer Cotton Cleanable or Dry Extendable media.



MAXIMIZE AIRFLOW
The OEM intake tube is highly restrictive and flattens out toward the center of the tube. S&B's intake tube doesn't flatten out, and is designed to minimize restriction with one clean line from the throttle body to the air box. Less obstruction means more airflow, and better performance.




LARGE CLEAR LID
Our signature large clear lid provides great looks. Featuring a rubber lid seal to keep out power robbing engine heat.




 

Installation Instructions

 
S&B Filters is a manufacturer of cold air intakes, filters and other performance parts, specializing in diesel/gas trucks and SUVs. Holding true to our goal, we engineer intake systems to greatly reduce airflow restriction, while still protecting your engine and test our product against our competitors following ISO 5011 standards. We keep our quality high and our pricing low by making almost everything ourselves in the U.S.


Breathe easy. Your engine and warranty are protected.
A mountain of dust and our 1/2 million dollar lab is how far we've gone to make sure your investment is protected.




Tested to a higher standard.
S&B tests to the internationally accepted ISO 5011 Standard when testing for airflow, efficiency and capacity. This is the same protocol used by most of the large automakers.

Airflow testing shows us how we compare to stock and our competitors. The goal is to beat both.

We test for efficiency to make sure that your engine is protected from debris while sucking in even more air. Lastly, we monitor the capacity of the filter to see how much dirt it can hold before needing to be serviced.



Precision and accuracy.

Our environmental control system is top of the line. S&B strives for accuracy and repeatability. In order to have dependable results, you have to have tight control over the humidity, temperature and barometric pressure.




Better Airflow

It's important to know how we stack up against stock and our competitors in order to be the best. We mount each intake system on our test equipment to measure the airflow from zero to the max CFM of the vehicle. We then compare the results and make design changes until we have maximized the airflow while still protecting your engine.




Protect your engine.
While airflow is important, it is equally critical to insure that your investment is protected. To do so, we first determine the max CFM the vehicle will generate at wide open throttle as it is more difficult to stop dust the greater the airflow. We then start pulling this amount of air through the intake while literally shooting fine particles of dust at the filter. Any dust bypassing the filter will be caught in the absolute blanket to determine the efficiency.

Some competitors have testing done at low CFMs in order to show higher efficiency rates, so beware.




We're not kidding.
Our testing is so controlled that we even heat the absolute blankets pre and post testing in order to remove the humidity. The absolute blankets catch any dust that gets past the filter during testing in order to determine the efficiency rate.

Removing the humidity insures that you are only weighing what actually bypassed the filter. Protecting your engine while providing better airflow is our top priority.
