Review on 🚀 K&N Engine Air Filter: High Performance, Premium, Washable Replacement Filter: Compatible with Toyota Truck and SUV V6/V8 (Tundra, Tacoma, Sequoia) 2014-2019, 33-5017 by Mike Goodwin

Your results are different from mine, but I've noticed a noticeable improvement in gas mileage. I drive to and from work the same way every day, so there are no real differences in my driving and I've noticed an almost 2mpg improvement in fuel economy. Depending on the vehicle, I get 23.6mpg where I got 21 and some changes. This filter will pay for itself over the next three months. In terms of performance, I don't notice a big difference. Maybe I'm just not tuning in, so I don't notice. I bought a filter for my wife's car and hopefully we will see the same increase in gas mileage.
