The A'PEXi Power Intake is the premier air filter designed to create pure horsepower. New funnel design, element material and air flow channeling characteristics make the Power Intake one of the most efficient air cleaners on the market today. By constructing the upper and lower funnel from a highly durable injected resin, engineers were able to construct the ideal shaped funnel previously not possible with the stainless steel material. Funnel shapes focused on increasing air speed without changing the flow direction of the intake air. The result is a high speed and smooth flow of air into the intake. Some of the problems associated with wet type cleaners, such as oil sticking to the air flow meter, are a thing of the past. The Power Intake is basically maintenance free. Filter replacement, when necessary, can be done at a very low cost.
