BBK 80mm TB disapointment
is all of this normal or did he get a dud? seems like he got riped off to me.
The reason you have to cut the bellow is because of the metal adapter reducer plate that comes with the t.b. , It pushes out your intake length 3/4 of an inch or so, so you have to trim the bellow to compensate for it, If not it will push the lid up and the hood will rub on the lid,
The gasket will also have to be trimmed because they made generic to fit more than one application.
Your friend would of been better off with a ported t.b.
Good luck with the car running normal because when i installed my bbk t.b. it messed with the IAC and messed with my idle so it had to be tuned
