The K&N E-0665 is a round, oiled cotton-gauze high-flow replacement element for the 6.2L V8 in the C7 Corvette. It drops into the factory airbox rather than requiring an intake system swap. The manufacturer describes its washable, reusable High-Flow media as layered, oiled cotton engineered to improve airflow and capture contaminants. Over a disposable paper element, the buyer gets a filter that is cleaned and re-oiled instead of replaced, backed by K&N's No-Hassle Lifetime Limited Warranty. Set expectations carefully. User forums report mixed results, with some owners noticing louder intake noise and better throttle response while others felt no measurable gain, so treat this as an affordable filter upgrade, not a power package.
Fitment is the first thing to verify. The manufacturer's page lists CHEVROLET CORVETTE STINGRAY V8-6.2L F/I, 2014-2018, while the part title references 14-15 and other sources cite 2014-2019 C7 models. Confirm your model year with the manufacturer before ordering. For installation, user forums describe the C7 airbox as the tricky part: one owner reported about 25 minutes on a first attempt, and another suggested taking the whole air box out for easier access. Search terms to use include K&N E-0665 C7 Corvette intake filter, LT1 Stingray airbox filter swap, and reusable oiled cotton Corvette air filter.

Yes. The manufacturer states the filter is reusable and engineered to last for the life of the vehicle. Cleaning intervals vary by source and driving conditions, so check the manufacturer's installation and care guidance.
This is a drop-in filter, but the C7 airbox is tight. User forums suggest disconnecting the mass airflow sensor connector and the intake tube, unfastening the airbox lid, and seating the new element fully before reassembly. One owner reported a warning message after reinstalling the airbox, which another forum member traced to an installation issue rather than the filter, so make sure every connector and clip is secure before starting the engine.
