The manufacturer Hiflo is the only filter producer that has its products tested and certified by the TÜV south Germany.The filters get compared to the original in all relevant criteria. The test can only be passed if the Hiflo filter can either match or beat the values set by the original. That way it is ensured that all filters fulifill the qualitiy standards of OEM products.
The warranty of the motorcycle remains untouched if a either matching or qualitavely better filter is used. (information according to TÜV south Germany)
Only high-quality materials are used for the production of the filters: adhesive from Germany, filter paper from Japan, Scandinavia or the USA, steel from Japan.
Countless different OEM versions have been combined to one filter. Only the best quality filter was taken as a reference and produced. With just a few filters, almost all Japanese, European and motorcycle models can be covered.
