Dual Funnel Air Filter

The APEXi Power Intake Replacement Air Filter (Part Number 500-A021) is engineered to optimize airflow and deliver pure horsepower. Its innovative Dual Funnel design, refined from previous models, channels air into lower funnels, improving flow characteristics for maximum efficiency. The filter element is constructed from a durable, dry density fiber material that provides excellent protection against foreign materials entering the engine while also decreasing ventilation resistance by approximately 10% compared to older models. Constructed with a highly durable injected resin for the upper and lower funnels, the Power Intake achieves an ideal funnel shape that increases air speed without altering flow direction. The lower funnel is specifically engineered with a 14-degree curve and positioned closer to the base for reduced drag and elimination of "dead spots." This dry-type filter design prevents oil from sticking to the air flow meter, offering a maintenance-free solution with cost-effective filter replacements when needed. Key specifications include an Outer Diameter of 160mm, an Inner Diameter of 85mm, and an Air Flow Diameter of 90mm. This filter is intended as a replacement for APEXi Power Intake systems and is compatible with a wide range of Japanese vehicles, including models from Mitsubishi, Nissan, Subaru, and Toyota. However, compatibility is based on manufacturer data for JDM cars, and fitment is not guaranteed; buyers are advised to conduct their own research. The product description also notes that adapter flanges are available separately for versatile mounting options.
