Green Filter USA — Washable High-Flow Air Filters & Intake Systems

Green Filter USA engineers washable, reusable performance air filters built for drivers who want more airflow, better filtration efficiency, and a filter that pays for itself over time. Manufactured in Italy and distributed in the USA, Green Filter products combine high-flow cotton gauze filter media with a durable wire mesh construction that outperforms disposable paper filters in both airflow and long-term filtration performance — without the maintenance headaches of competing reusable filter brands.

High-Flow Air Filters

Green Filter's panel and conical filter lineup covers OEM drop-in replacement applications and universal intake builds across a wide range of domestic and import vehicles. The multi-layer cotton gauze media is oiled from the factory and engineered to flow significantly more air than OEM paper filters at equivalent filtration efficiency — reducing intake restriction and allowing the engine to breathe more freely across the RPM range.

Unlike single-layer gauze filters that sacrifice filtration for flow, Green Filter's multi-layer construction maintains particle capture efficiency while delivering the airflow gains that translate to measurable throttle response and horsepower improvements on modified and stock engines alike. The filter media is cleanable and re-oilable, with a service life measured in years rather than oil change intervals.

Intake Systems

Green Filter produces complete cold air and short ram intake systems for select performance applications, combining high-flow filter elements with optimized intake tubing for maximum airflow from the filter to the throttle body. Intake systems are application-specific, engineered to route incoming air away from underhood heat sources and into the filter element efficiently without turbulence-inducing bends or restrictions.

Filter Maintenance & Reusability

Green Filter elements are cleaned using a dedicated filter cleaner that breaks down accumulated dirt and oil without damaging the cotton gauze media. After cleaning and drying, the filter is re-oiled with Green Filter's filter oil to restore filtration efficiency and tackiness before reinstallation. A properly maintained Green Filter element can last the life of the vehicle, eliminating the recurring cost of disposable OEM replacement filters over time.

Common Applications

Green Filter USA produces air filters for a broad range of domestic and import vehicles — including Chevrolet Camaro, Corvette, and Silverado, Ford Mustang and F-150, Dodge Challenger and Ram, BMW, Audi, Volkswagen, Honda, Toyota, Subaru, and many more. OEM drop-in panel filters are available for vehicles where a direct replacement is preferred, while conical filters serve universal and custom intake applications.

Build Quality & Italian Manufacturing

Green Filter elements are manufactured in Italy using high-quality cotton gauze media, precision wire mesh frames, and durable rubber end caps that seal correctly against OEM and aftermarket airbox housings. The construction is built to withstand the vibration, heat, and oil exposure of the engine bay environment without delaminating, collapsing, or losing shape over time. Each filter is inspected before shipment for correct dimensions and media integrity.

Installation Notes

Green Filter OEM drop-in replacements install directly into the factory airbox using the existing hardware — no modification required. Conical filters for custom intake applications require a compatible intake tube with the correct inlet diameter. Initial installation on a new filter requires no additional oiling — filters are pre-oiled from the factory. Re-oiling is only required after cleaning. Allow the filter to dry completely after cleaning before re-oiling and reinstalling to prevent oil contamination of the MAF sensor.
