ITG Profilter foam air filter for original airbox WB-531

Discover the Profilter foam air filter, designed specifically for original airboxes with reference WB-531. Handmade in England, this high-performance replacement filter uses the same materials as those used in Formula 1 and WRC. Thanks to its innovative TriFoam concept, comprising three layers of foam with high filtration capacity, it efficiently captures dust particles down to 5 microns. It allows greater airflow than traditional cotton or paper filters, providing better fuel economy at constant speed and increased power by reducing pressure drop. Washable and reusable, it can last up to 10 years. Pre-oiled, it is ready to use. Remember to use the cleaning kit, reference CLK1, to maintain your filter. This product is compatible with the Mazda RX-7 (FC, FC13, FD13) 1.3 [Turbo, Twin Turbo] from 1985 to 1991, with the RE13B engine.
