After alot of research, I finally purchased a filter for our Late Model and could not be happier. We ran paper filters before and had to run grease on the cleaner and it seemed dirt still made it through. Now with the R2C filter we do not have to mess with the grease and our carb is cleaner. We will now buy one for our modified.

Let it breathe!  Help your JK engine to help you.

Your JK V6 engine is basically an air pump!

The factory provides JK's with basic, low cost and relatively ineffective engine breathing/filtering capability. The factory engine air supply is designed to be a compromise of many criteria.  Through extensive analysis, R2C engineers have discovered the impediments to feeding your Jeep engine with the air it requires to perform at the highest levels.  Now, this breakthrough, Black Hex technology allows your air pump to breathe all the cooler, cleaner air it needs!

The factory engine intake system has a great deal of restriction. Almost 16" of water grains are required to move air into your engine during high demand driving. R2C has reduced this level to 5.7" water grains on the manometer, a laboratory device which measures how hard your engine has to work just to bring in the air it requires to perform at maximum levels.  That's one-third the restriction of the factory air supply system! 

The factory system makes bringing air into your engine 200% harder!

Remember, we have designed sophisticated, military engine breathing systems for decades and now we can offer JK owners this advanced technology that separates R2C from every would-be "performance" company in this spectrum.

We design and build "systems" and don't use off the shelf components.  This system synergy integrates specifically designed  JK components that include criteria such as correct tube volume and CFD designed shape, intake temperature barriers and unlike others that rely on generic filter producing companies, we design and manufacture our Black Hex and Extreme Series filtration in-house.


Daily Driving:

The R2C Black Hex Advantage - Don't forget, free engine breathing also makes daily commuting much easier on you and your JK engine. Since it works much less hard to bring in cooler and cleaner engine air, you benefit from this improved efficiency. Free breathing can pay for itself at the pump too!
