The Mines VX Air Filter for the Nissan R35 GT-R is made of three layers of cotton, aluminum mesh, and a special oil. The VX Air Filter for the Nissan R35 GT-R provides excellent air filtration without causing any turbulence in the airflow. By increasing the air mass (170% compared with the stock filter), this product alone can improve your power by 3 to 5 hp. However, combined with VX-ROM, the power improvement will be more impressive.
This product is also washable. Based on the Mine's test data, even after washing over 35 times, the reduction of the air flow was limited to only 3%.
