Replacement Conical Filter for RT992M200701 & S1/Polo Kit – RT992M202100

THREE LAYER FOAM FILTER

An intake system is only as good as the filter. This kit comes complete with a tried and tested Revo three-layer foam filter with an impressive 857cm² surface area, supported by galvanised, epoxy-coated mesh to ensure the filter cannot collapse. The filter has a large 180mm external diameter body and a smooth radius aluminium bell mouth, specifically designed for optimum airflow from the filter to pipe-work. Revo three-stage foam filters work very differently to conventional paper or cotton-gauze, which are surface filters designed to trap particles on the outer layer, instantly causing restriction.

Revo foam filters work by trapping dirt particles within each of the oiled foam layers, allowing air to negotiate its way through the filter, reducing restriction and offering much longer service intervals. We tested the filter at a leading motor testing centre ‘Mira’ on industry recognised dust load test. On a full dust load test, the foam filter was found to still be 99.1% efficient, filtering down to 5 microns while offering the least amount of restriction over similar products.
