I installed the K&N filter in my 2018 Tour-X and a few days later made a 450 mile round trip down to Phoenix, Arizona. Others have stated a little loss in mileage however I showed a little increase. As far as increased performance, very noticeable. Makes the turbo preform even better. I have used K&N products for many, many years in trucks, cars and motorcycles. Never a disappointment and well worth the money spent. Would highly recommend using this product on the Buick Tour-X.
