Bully Dog's enclosed intake system keeps hot air out of the intake stream by targeting cold air sources and specifically designed to optimizing airflow. A high flow 8-layer cotton gauze air filter provides maximum filtration to protect your motor without limited airflow. The injection-molded design upgrades the engine bay for a custom finish.
