Our 11th Gen Civic 2.0L High Volume Intake system utilizes a 4" oiled cone filter and 1-piece High Volume MAF housing to allow maximum airflow while delivering proper fuel trims. The HDPE rotomolded air box utilizes the factory air guide + seal for optimal airflow and heat-soak reduction. Custom molded 4-ply silicone with receiving grooves allows for all components to be safely attached without obstructing airflow. Customers can also access the air filter for maintenance without removing the air box!
