    Id say 3mm and 4mm and just get some force on it if its a bit tight as you wat it to be tight not loose like a wizards sleeve with a zip tie to hold it in place as it can loose vacuum if the sealing isnt right lol i have 3mm on my 1.8TQS and i struggleg to get 3mm on the forge 007p but with some force its on and not coming off without a good yank !!
