AVOTurboworld's high-flow pop-in flat panel air filter for the factory OEM air box has been designed specifically from sturdy cotton fibre. It increases air flow, allowing the engine to make more power and torque. Yet thanks to a special dry film it has equal rates of engine protection. This dry film design does not use oil, like most other performance filters, which keeps your MAF from being damaged from excess oil. Thanks to its high-tech design the AVO panel air filter is washable, extending the life beyond your standard drop-in air filter. You simply need to soak it in warm, soapy water, rinse it out with water, then let it air dry.
