K&N's Fuel Injection Performance Kits are designed to promote performance in stock fuel injected engines by allowing air filtration with least resistance in air flow. The benefit can be felt in throttle response. In addition to the filter, kits have uniquely designed adapters, creating a radius entry that reduces restriction and allows the engine to breathe a greater volume of air. Check local regulations concerning emissions & aftermarket air cleaner assemblies. Because it is not OE equipment it could fail visual inspection.
