These filters simply replace the existing standard air filters (elements) and offer reduced restriction of the air intake system  thus optimising horsepower, throttle response and torque. Simple to fit, just remove the original filter from the air box and “drop in”  the GREEN Filter Europe Cotton replacement air filter element. They are also compatible for both Group-N and Group-R Motorsport regulations*.

Rather than paper, the filtration material used is a woven natural cotton  impregnated with a light oil. This material not only improves air  flow, it is also better at filtering tiny particles than paper – and  can be cleaned and re-used. Woven natural cotton gauze filters do not clog up as quickly as paper so service intervals can be longer. The Green woven natural cotton filters can easily be cleaned and reconditioned with one of the Cleaner/Oil kits available, thus saving on servicing costs.
