High-performance, universal filtration. The K&N E-3380 is a premium, high-flow air filter designed for custom intake systems and aftermarket air cleaner assemblies. Built with K&N’s signature oiled cotton gauze, it provides superior airflow and engine protection for performance builds.

How to Confirm Fitment

This is a universal part, not a vehicle-specific replacement. Do not search by your car’s make and model. To ensure this fits, measure your current air cleaner housing. If your existing round filter element is 178mm (7") outside diameter and 76mm (3") tall, the E-3380 is the correct high-performance upgrade for your assembly.

This filter is a favourite for custom hot rods, street cars, and vintage restoration projects. It is designed to fit standard 7-inch round air cleaner assemblies, which are commonly used on 4-barrel carburetors (such as Holley, Edelbrock, and Demon) that feature the industry-standard 5-1/8" air horn neck.

Key Features

  • High-Flow Design: Engineered to increase horsepower and throttle response by minimizing airflow restriction compared to paper filters.
  • Washable & Reusable: Simply clean, re-oil, and reinstall; this filter is built to last the lifetime of your project.
  • Durable Construction: High-quality cotton gauze media supported by robust wire mesh for consistent performance under vacuum.
  • Universal Application: Ideal for custom air boxes and aftermarket 7" diameter air cleaner kits.

NZ Air Filter Expert Advice

Pro Tip: Before installing, check your housing for clearance. Because this is a high-flow filter, it performs best when it has a small gap between the top of the filter and the lid of your air cleaner housing to ensure even airflow. If you operate in very dusty or off-road conditions, we highly recommend pairing this with a K&N Precharger/Wrap (Part #E-3380PR) to keep the cotton gauze clean and extend the service interval.
