Perfect fit for 2018 grand touring
Size: size for 6 Turbo/CX5 Turbo
It fit perfectly in my 2018 Mazda 6 Grand Touring. I replaced both filters & had no issues installing them. They feel really well made. I could notice a difference in smell right away. It wasn’t bad, I just knew I had replaced them LOL. The value is great for what you get.
