Designed to promote performance in fuel injected stock engines by creating air filtration with the least resistance in air flow. The benefit of low resistance air filters can be felt directly in throttle response. These kits have uniquely designed adapters. These adapters create a radius entry which reduces restriction and allows the engine to ingest an even greater volumn of air. To design such an assembly, two factors must be considered; the air filtering element and the air filter adapter. The FIPK combines a precision high flow K & N air filter element with other necessary components, depending on the specific application.
