Gary T from Parma Heights, OH said, "Noticed an immediate increase in low end power. The car was already very powerful at low speeds but the filter caused a difference that could be felt.Since the Lexus is my second car, it takes a while to put enough miles on it to accurately determine if there's a miliage improvement. Since I keep record of all fillups and miliage, I should have that information soon. I will post a followup on any miliage impact at that time"
