The K&N 63-3081 AirCharger is a cold air intake built for the LT1 6.2L V8 in the C7 Corvette Stingray. It replaces the factory airbox and accordion hose with a black, high-density polyethylene tube, and the manufacturer's copy says the tube is designed to route air into the throttle body. A red, oiled cotton-gauze K&N RP-5285 filter and a heat shield sit in the former airbox space, which keeps the intake slightly cooler than the factory setup. Buyers comparing it with a cheaper drop-in filter should know that enthusiast forum owners often report that most major CAI brands perform about the same on the LT1, so the real case for this kit is its reusable filter, its engineered airflow path, and K&N's warranty. The filter is washable and rated for up to 100,000 miles between cleanings, depending on driving conditions, which offsets the higher upfront cost over time. Keep in mind that the kit is not legal for sale or use in California or other states that follow California emissions standards.
The tube accommodates the factory mass airflow sensor and crankcase vent hose, so the stock sensor carries over rather than being replaced. Owners on enthusiast forums suggest that oiled filters should be used carefully, since excess oil can contaminate a mass airflow sensor. Most installs are described as taking about 90 minutes or less using factory mounting points and basic hand tools. Shoppers searching for a 2014-2015 C7 Stingray LT1 cold air intake, a K&N 63-3081 AirCharger install, or a reusable LT1 6.2L intake filter should confirm the exact model year and body-style coverage before ordering, because listings vary.
Yes. The manufacturer states that the intake tube accommodates the factory mass air sensor and the crankcase vent hose, so the stock sensor is moved into the new tube rather than replaced.
No. The manufacturer's product copy states the kit is not legal for sale or use in California or in other states that have adopted California emissions standards. Check your state's rules before buying.
Owners on user forums caution that an over-oiled filter can contaminate the mass airflow sensor. Clean and re-oil the RP-5285 filter carefully, using only the amount of oil the manufacturer specifies, and avoid over-oiling.
The manufacturer rates the install at about 90 minutes or less and says it uses the existing factory mounting points, so this is a realistic weekend job for a home mechanic. Enthusiast guides for C7 intake swaps describe removing the radiator air duct first, then disconnecting the vent hoses and intake tube, and removing the factory airbox with a 10 mm socket. Owners on user forums suggest having 7 mm and 8 mm nut drivers, a 10 mm ratchet, and an extension on hand, and the manufacturer's installation sheet should be consulted for the exact hardware list. Common gotchas include clamps that need careful tightening, reconnecting the mass airflow sensor and vent lines correctly, and checking the intake for clearance and alignment after the first drive.
