This is Integrated Engineering's direct replacement filter for its 5-inch velocity stack cold air intakes, the same filter used across the majority of IE's intake lineup. It is a dry filter designed for high flow and a precise fit to the integrated velocity stack on IE's intake housings.The filter can be cleaned and reused many times over its life; once it becomes difficult to clean or shows heavy staining, that is the sign it is time to replace the element rather than keep cleaning it.Important Compatibility InformationThis filter is a dry design; IE does not recommend oiling it on turbocharged or forced-induction vehicles, since excess oil can affect sensor readings on those applications.Features Direct replacement for IE's 5-inch velocity stack intakes High-flow performance filter design Washable and reusable What's Included Integrated Engineering 5-inch replacement air filter (x1) Filter clamp (x1) Product Specifications SKU / MPN: IEINCC1-3A Fitment: Integrated Engineering intakes built around a 5-inch velocity stack Frequently Asked QuestionsWill this fit my IE intake?It fits IE intakes built around a 5-inch velocity stack, which covers most of IE's cold air intake lineup.
