Why this part fails — and what we do differently
Filtration efficiency is where a cheap air filter quietly costs you an engine. We build this element with multi-layer composite media, resin-impregnated end caps and a nitrile gasket, so the pleats hold their geometry under a cold-start viscosity spike instead of collapsing and letting unfiltered oil bypass the media.
Ordering, packing and warranty
Single pieces ship for urgent breakdowns; consolidated container or air freight is available for stock orders. Each part is packed individually in a carton with the part number labelled, and we send photographs of the actual goods plus a measurement report before shipment. Warranty: 6–12 months against manufacturing defect under normal operating conditions.
