The K&N AirCharger 63-3099 air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Camaro ZL1 models (see vehicle applications). K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Camaro ZL1 engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 63-3099 air intake tube is made almost completely out of ultra-lightweight carbon fiber. Included is a K&N high-flow air filter and a heat shield that directs cooler air into the custom molded intake for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
