I have used K&N products for years. Just bought a 2017 4RUNNER. very easy to install. Fit was perfect. I noticed better throttle response with somewhat better gas mileage. Engine breathes better. Very happy with this product.

My vehicle seems to be running better, quicker off the line with less effort. I recently took a six hour freeway trip and gas mileage was up a few tenths of MPG, even in Los Angeles area traffic of stop and go. Great quality made product, made for the lifetime of your vehicle. Installed in minutes with very little effort, just unclipped the air box clips, removed the old factory filter, wiped out any remaining dirt in the factory air box and placed the K&N filter in (exact fit) re-clipped.
