The throttle body is either 48 or 52mm, But you'll have to take it off and look. 52mms have 52 stamped on the flange.Having spent the afternoon clearing out the back half of our garage, meaning i could get to the boot of the F, so for the first since i've had the car i thought i'd find out what the engine looked like.
Whats the easyest way of finding which throttle body i have. Here mine
Also any clue on what this sticker means
