I bought these for my 2015 Nissan 370Z Sport Model. Installed them last month and have been really pleased with their performance. Throttle response has been much better, smoother and more predictable. Engine doesn't seem to be straining and I even saw an increase in gas mileage. Not much, maybe 3 mpg's, but it's better than what it was. Thanks K&N, I'll be back for more of your great products.
