AVOTurboworld's power filter kit & air box combo specifically for the BRZ/FRS/86 has all the hardware to fit with the AVO Turbo Kit. The full kit routes air from the front bumper area and this is best because it is the coolest air is available, especially when in motion. It comes with a fibreglass air scoop to a powder coated steel box and a carbon fibre top lid. It is truly simple to install on your own, and is a good, cheap power-adder that works well with stock or modified setups. By using the AVOTurboworld air box, you can be sure of getting all the cold air to your engine! AVO uses a washable and fully re-usable hi-flow filter that 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 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, and then let it air dry. The power filter and airbox kit also includes all the mounting brackets, bolts, washers, nuts, plastic clips and installation instructions to make for a correct installation.
