More Air

One of the easiest and most rewarding modifications you can do to your Jeep is installing a cold-air intake in place of the factory air filter box and inlet tubing. The factory paper panel filter elements do a good job of keeping particulate out of your engine and the intake tubing quiets all but the faintest whisper from the air intake charge, but at a cost of air flow, power, and mileage. Good for the average consumer who doesn’t care about stuff like better power or economy, but not so great for enthusiast like you and us who want more.

We got our hands on the company’s relatively new 3.8L system for our ’07 Rubicon Unlimited. We also had a chance to install the latest Ram-Air intake on a ’12 Unlimited Sport with the 3.6L, but that vehicle was a loaner and we didn’t have time to garner any long-term numbers. But on our ’07 Wrangler, our efforts were rewarded with an immediate and noticeable power increase. Even with 35-inch tires and an automatic transmission, the 3.8L in our Rubicon could chirp the rear tires when punched from a dead stop and pulls to redline much nicer after the Ram-Air was installed. And we are seeing a very definite 1 mpg increase in our overall fuel economy. Not bad for 10 minutes’ worth of work!
