These days no one wants to pay more for gas, but at the same time everyone wants more power from their TJ. The answer to both of these problems is a new Wrangler cold air intake system for your TJ. The idea is pretty simple - take cold air from outside your Jeep, and force more of it into the TJ's intake, allowing the TJ to breathe better. This will produce more torque and horsepower when giving your Wrangler better fuel economy. Sounds to good to be true right? well, even MOPAR has begun building a cold air intake system, proving that even the manufacturer believes in the technology!
