LS4 TB Adapter coupler
Quality is very good, it’s is a VERY snug fit and took a lot of work to get on for a coupler but that isn’t a bad thing. At least you know you won’t have any problems with it coming off!
For some reason I always have a hard time putting the coupler on the throttle body after it’s on the intake but other than that it has an amazing quality and the zzp emblem on it looks outstanding I even drilled a hole to put my nitrous line even tho I also have the ls4 spacer plate
