I purchased a replacement K&N air filter for my 2015 C7 Corvette. It was due for a replacement of the OEM air filter. Installation was easy. I'm reticent in believing that the filter will increase the horsepower and fuel economy of the car but I do believe that the filter is a better quality than is the OEM filter, and it can be cleaned and reused. In the long run I believe the K&N replacement filter to be a wise and economical decision. My C7, as are my other two cars, is now equipped with a K&N oil filter, a K&N cabin air filter, and a K&N air cleaner filter.

After installing the K&N Filter in a 2014 Corvette Coupe, my quarter mile speed, with no other modifications, increased from 112 MPH to 118 MPH. Enough said.

Arrived sooner than expected, have used K&N products for 15 years. Would recommend this product to anyone wanting to keep their auto in great condition. Just put this one on my 2016 Corvette Stingray, big jump in gas mileage, also have one on my 04 Silverado.

I've read some have issues replacing their K&N on their C7. I did mine by myself with no issues. Took my time replacing, 30 minutes start to finish. Can't believe Bowling Green purchases their paper filters from Thailand.

Really can't tell any improvement due to not running it before and after in the 1/4 or 1/8 mile. If any improvement would show on your time slip in similar DA conditions. No noticeable change in normal driving (sound or performance). The OEM filter that is made in Thailand look nice and has a lot of pleats and must flow good as it is the same filter that comes in the Z06. With the filter in my stock un-tuned base C7 A8 with 285/35R19 M/T DR's Best 1/8 mile 60' 1.677 and best MPH of 94.5 ET of 7.47. The filter is the best priced OEM replacement filter so for the price you could give it a try and see what happens. I would be willing to try the Complete system for K&N if the provided it for me to test at the strip and give them feed back of improvement in real world ET and MPH as I am close to them.
