I liked the fact that it was made to look like a real replacement filter (it's the one that fits Monster Ball), it's like a real filter which means it bolts on is but it's a piece of junk as it sounded like a boeing max attached to my dyson monster car as there is a loud horrible noise from not fitting properly in the wheel. It's not curable so make sure to buy it if you like it if your car sounds like a jet but damn sure if it doesn't fit right it won't even filter properly.
