The Ranger 2.3L Cold Air Intake Kit. The ROUSH Performance Cold Air Intake delivers greater performance over the stock intake - increasing airflow and producing power gains of up to 8 lb-ft of torque over stock with an intake swap alone. This CAI system features a custom engineered transparent cover while maintaining the factory airbox snorkel and increasing airflow. The included ROUSH conical-style dry element filter has 21 percent more surface area than the factory filter and requires no oiling and is easily washable for reuse. No modifications are needed for installation, just bolt-on and go! Installation of the ROUSH Performance CAI will also not void your factory warranty. This cold air kit is also backed by the ROUSH 90-Day Limited Parts Warranty.
