I have the Mugen carbon gearknob if that's what you mean, I was very iffy about it at first when it came in the post but it feels good once you get used to it, you get a nice grip from it, fits nicely in your hand and it looks pretty sweet too never even had OEM as it was taken off before coming over to me on boat but I have never been tempetd to go OEM as I love my Mugen, can get pic of it in the car if you want to see the size of it
