As the inventor of the reusable cotton air filter, unsurprisingly K&N continues to lead the market in performance air filters in all applications. This K&N pod filter represents one of their most popular products, showing excellent air flow gains, in a size perfect for most turbocharged and naturally aspirated engines. Although this pod filter may not directly give large gains in horsepower and torque, combined with other modifications this filter can significantly improve the throttle response and feel of the vehicle. This K&N pod filter is constructed from lightly oiled cotton media, folded and secured with fine mesh, presenting distinct advantages over traditional foam pod filters. Namely, that the K&N filters folded design allows the filter to hold shape, even under incredible levels of vacuum, where other filters may collapse. Furthermore, this folded design also greatly increases the surface area of the filter, allowing the engine to breathe cleaner air, easier. This filter is also designed to be reusable, as opposed to most other filters which need to be thrown away after a short life. Instead, this filter can simply be re-oiled, generally after around 50000km of driving, or simply when it starts to lose its colour.
There are rules and regulations that cover the installation of aftermarket air filters in Australian road vehicles. As these rules differ from state to state, please check with your local transport authority for further information.
