Prevent performance drops on your induction kit with this premium Green Filter Air Filter Cleaning Kit, commercialized under the official part number GREEN-NH01. Comprising a powerful degreasing cleaner fluid and a specific high-adhesion air filter oil spray, this complete pack restores the filtration properties and original breathability of your cotton gauze filter.
An absolute requirement during every routine service or for the regular maintenance of your cold air intake or dynamic airbox setup, this premium treatment blocks horse power loss and shields the MAF sensor of your performance vehicle.
The high-output engines found in modern performance cars rely on a constant, unrestricted supply of clean, cold ambient air to achieve optimal internal combustion. If you run a high-flow cotton gauze sports filter—whether it is a panel replacement filter in the stock airbox, a direct open induction kit, or a carbon dynamic enclosure—without ever servicing it, road grime, pollen, and thick soot will saturate the cotton layers. Without using this authentic Green Filter cleaning kit (part number GREEN-NH01), the mechanical consequences are immediate. Intake airflow drops significantly, forcing the engine management ECU to overcompensate for the restriction. You lose instant throttle response, your power band flattens out at high RPM, and your fuel consumption increases. Furthermore, a heavily clogged element can eventually allow abrasive microscopic dirt to pass through the mesh, scoring your cylinder walls and fouling the hot wire filament of your Mass Airflow (MAF) sensor, triggering check engine lights and permanent performance drop-offs on your performance car.
A reusable sports air filter must never be washed using harsh chemicals like gasoline or brake cleaner, nor should it be blown dry with compressed air, as this permanently destroys the delicate cotton weave. Neglecting to apply the dedicated tack oil spray after washing leaves your engine vulnerable to poor fine-particle retention.
The GREEN-NH01 maintenance kit features two highly specialized chemical products formulated by Green Filter to preserve natural fabric materials. The active cleaner fluid works via deep emulsion to dissolve heavy oil residues and caked-on road grime without altering the tight structural grid of the cotton. The aerosol oil spray then leaves a light, protective colored film. This specialized fluid features a strict surface tension rating that traps microscopic particulates using an electrostatic effect while permitting maximum air volume to pass through. It is the mandatory tool needed for your routine intake maintenance or to sustain a high-flow performance customization project on a sports chassis.
This universal cleaning kit is fully compatible with all major brands of washable cotton gauze sports air filters (Green Filter, K&N, BMC, Pipercross cotton variants) equipping the following vehicle ranges:

How often do I need to service my performance filter using this cleaning kit?
We generally recommend servicing your cotton air filter every 10,000 to 15,000 kilometers (approx. 6,000 to 9,000 miles) under regular road driving conditions. If you frequently drive on race tracks or commute in high-dust environments, it is best practice to reduce this interval to 5,000 kilometers to keep intake pressure drops at zero.
Can the blue or red oil contained in the GREEN-NH01 kit damage my MAF sensor?
No, provided you follow the simple directions. After washing and thoroughly air-drying your filter, apply the oil spray in a light, uniform mist. The most common mistake is over-saturating the cotton fabric, which causes excess oil droplets to bleed into the intake tract and coat the delicate hot wire of the Mass Airflow sensor. A light coat is all that is required to restore the filtration shield.
The efficiency of your ECU remapping and engine build relies completely on the purity of the incoming air stream. Do not let a suffocated filter restrict your acceleration performance and dull your high-speed driving enjoyment.
