K&N E-0665 Air Filter Product Reviews

Tuesday, September 18, 2018 - Part E-0665
Pleased with part and my installation went well into my 2016 Z06 Corvette. However, as soon as I started the car I received a MIL light indicating an issue with the engine. I did not have a Code Reader so I don't know what code was thrown. To install the filter I had to remove the MAF sensor. However, I only had it off WITHOUT the ignition being on. I contacted the Tech help which was quite helpful. Joel told me to drive it for a day or two and the code would clear. I drove it (note: it seemed to run fine) and after the third cycle on/off the code cleared by itself and I haven't had another issue. It would be VERY helpful if you put a small note in with the filter saying something like MIL light may come on after installation. Run vehicle for a minimum of 3 on/mileage/off cycles and code should clear. Call K&N Tech if code does not clear after X number of restart cycles.

Was a bit of a tight fit into the air box of my 2019 Z51 but the overall replacement process was a simple case of following the GM owners manual instructions, 30 minutes and no special tools. Immediately noticed a smoother throttle response and the 4 performance exhaust even sounds less labored. My 6th vehicle in a row where I've purchased a K&N air filter, wouldn't consider anything else. Improved performance, better fuel mileage and its re-usable, best of all worlds.

Replaced stock air filter with K&N, it was a direct replacement for my 2015 Corvette Z51, I noticed after the installation that the throttle response felt quicker and that the engine had a little better pickup and sound, I had K&N's on other vehicles and motorcycles and they ALWAYS perform excellent and are easy to maintain, I also replaced the cabin filter with a K&N carbon unit to help clean the air and keep the dust down on the interior of the corvette, I personally do not think there is a better aftermarket filter for the price, ease of installation and longevity, keep making a great product.
