K&N Custom Racing Assembly Carbon Fiber 4in Air Box w/o Base - Large

K&N's Sprint Car Style Air Boxes are a lightweight yet tough choice for racers who've been using traditional multi-Siamese stacks. Made from ultra-light carbon fiber, these air boxes offer great airflow for your racing needs. Like all K&N filters, it's a washable and reusable air filter. Just use K&N oil and cleaner to keep it in top shape.

Using your K&N air box is easy. Just install it in your racing vehicle where it can get good airflow. When it comes to maintenance, it's important to check the filter regularly. If it looks dirty, it's time to clean it. To clean the filter, use K&N cleaner. Soak the filter in the cleaner, then rinse it gently. After that, let it dry completely. Once dry, apply K&N oil evenly to the filter. This will help it trap dirt and debris. Remember to always follow the instructions on the K&N cleaner and oil products. Also, make sure the air box is properly installed to avoid any air leaks. With proper care, your K&N air box will serve you well for many races.
