The K&N 63-3081 Air Intake fits some Chevrolet Corvette models. See vehicle applications link for details.
The K&N 63-3081 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Corvette models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 63-3081 air intake comes with an ultra-lightweight carbon fiber K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized oval cone-shaped 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 usually in 90 minutes or less using existing factory mounting points requiring commonly available tools to do the job. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-3081 Air Intake Product Reviews

The parts diagram showed fasteners with washers, but the written instructions did not specify whether or not a washer was used. It would be nice if they did. It would also be nice for the instructions would say why the radiator hose needed to be cut from the tee. Looks good under the hood.

I installed this kit on my 2015 Stingray. The instructions were clear and the parts all fit pretty well. I can definitely feel a difference, especially accelerating in higher gears. I recommend.

The cold air intake that I purchased for 2015 Sting Ray made a huge difference along with a flash tune. I'm very happy.

The installation went well for the most part except there is some self figuring out with the coolant hose replacement and routing, nothing too hard to figure out yourself. I was satisfied with the sound; beefy and you can hear a vaccum at a higher throttle(sound awsome). Definitely brought out more sound to my modify exhaust. I recently removed my AFE intake and I definitely felt and hear the difference with the K&N, there is no lag response when hitting giving it gas. Highly recommend going with K&N.

I was pleased that K&N came out with this filter. The directions are easy to follow and the final installation is excellent. It really cleaned up the engine compartment. The added horsepower and torque are great.
