The LC Engineering Pro Air Intake Kit is designed to replace your restrictive stock air box and tube assembly. The kit incorporates an open element, washable K&N air filter to increase airflow and save you the time and expense of buying replacement air filters in the future. When the filter gets dirty just contact one of our sales reps and we can get you a service kit right away! Our kit also includes a mandrel bent stainless steel tube to keep a nice even flow of air to your engine, no kinks or ridges to impede the airflow. This tube is then ceramic coated and polished to retain all that cold air in the tube and repel the heat created inside the engine compartment. We also supply silicone couplers to attach everything together. You will not find a more complete kit anywhere for your 3VZ engine!!!
