ITG products are regularly used at the top level of motorsport, most notably including F1, World Super Bikes, 24 hours of Le Mans and WRC. This close association with the pinnacle of motorsport translates to the best possible filtration and increased air flow solutions for your road car.

ITG's foam technology is industry-leading (proven by their use in Formula 1 racing). Unlike the common cotton gauze filters, these foam filters will perform equally as well as new after being cleaned and re-oiled. We offer ITG's line of OE replacement filters (ProFilter) as well as their universal fit conical and cylindrical filters (Maxogen) for those of you wanting to upgrade the filter in your aftermarket intake kit.
